Bump 0.13.0 (#20336)

## Summary

From #17371

In #17371, `DivergentType` was introduced to prevent type inference for
recursive functions from diverging and causing panics. This turned out
to be useful for other divergent type inferences
(https://github.com/astral-sh/ruff/pull/17371#discussion_r2329337965),
so I extracted the introduction part of `DivergentType` into this PR so
that we can use it without waiting for the merge of #17371.

Note that this PR only introduces `DivergentType` and does not actually
address divergent type inference yet. Please refer to
https://github.com/astral-sh/ruff/pull/17371/files#diff-20b910c6e20faa962bb1642e111db1cbad8e66ace089bdd966ac9d7f9fa99ff2R542-R622
etc. when implementing handling of divergence suppression using this
type.

 # Breaking Changes
 
+## 0.13.0
+
+- **Several rules can now add `from __future__ import annotations` automatically**
+
+    `TC001`, `TC002`, `TC003`, `RUF013`, and `UP037` now add `from __future__ import annotations` as part of their fixes when the
+    `lint.future-annotations` setting is enabled. This allows the rules to move
+    more imports into `TYPE_CHECKING` blocks (`TC001`, `TC002`, and `TC003`),
+    use PEP 604 union syntax on Python versions before 3.10 (`RUF013`), and
+    unquote more annotations (`UP037`).
+
+- **Full module paths are now used to verify first-party modules**
+
+    Ruff now checks that the full path to a module exists on disk before
+    categorizing it as a first-party import. This change makes first-party
+    import detection more accurate, helping to avoid false positives on local
+    directories with the same name as a third-party dependency, for example. See
+    the [FAQ
+    section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc) on import categorization for more details.
+
+- **Deprecated rules must now be selected by exact rule code**
+
+    Ruff will no longer activate deprecated rules selected by their group name
+    or prefix. As noted below, the two remaining deprecated rules were also
+    removed in this release, so this won't affect any current rules, but it will
+    still affect any deprecations in the future.
+
+- **The deprecated macOS configuration directory fallback has been removed**
+
+    Ruff will no longer look for a user-level configuration file at
+    `~/Library/Application Support/ruff/ruff.toml` on macOS. This feature was
+    deprecated in v0.5 in favor of using the [XDG
+    specification](https://specifications.freedesktop.org/basedir-spec/latest/)
+    (usually resolving to `~/.config/ruff/ruff.toml`), like on Linux. The
+    fallback and accompanying deprecation warning have now been removed.
+
+- **[`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name) (`PD901`) has been removed**
+
+- **[`non-pep604-isinstance`](https://docs.astral.sh/ruff/rules/non-pep604-isinstance) (`UP038`) has been removed**
+
 ## 0.12.0
 
 - **Detection of more syntax errors**

 ### Breaking changes
 
-- **Detection of more syntax errors**
+- **Several rules can now add `from __future__ import annotations` automatically**
 
-    Ruff now detects version-related syntax errors, such as the use of the `match`
-    statement on Python versions before 3.10, and syntax errors emitted by
-    CPython's compiler, such as irrefutable `match` patterns before the final
-    `case` arm.
+    `TC001`, `TC002`, `TC003`, `RUF013`, and `UP037` now add `from __future__ import annotations` as part of their fixes when the
+    `lint.future-annotations` setting is enabled. This allows the rules to move
+    more imports into `TYPE_CHECKING` blocks (`TC001`, `TC002`, and `TC003`),
+    use PEP 604 union syntax on Python versions before 3.10 (`RUF013`), and
+    unquote more annotations (`UP037`).
 
-- **New default Python version handling for syntax errors**
+- **Full module paths are now used to verify first-party modules**
 
-    Ruff will default to the *latest* supported Python version (3.13) when
-    checking for the version-related syntax errors mentioned above to prevent
-    false positives in projects without a Python version configured. The default
-    in all other cases, like applying lint rules, is unchanged and remains at the
-    minimum supported Python version (3.9).
+    Ruff now checks that the full path to a module exists on disk before
+    categorizing it as a first-party import. This change makes first-party
+    import detection more accurate, helping to avoid false positives on local
+    directories with the same name as a third-party dependency, for example. See
+    the [FAQ
+    section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc) on import categorization for more details.
 
-- **Updated f-string formatting**
+- **Deprecated rules must now be selected by exact rule code**
 
-    Ruff now formats multi-line f-strings with format specifiers to avoid adding a
-    line break after the format specifier. This addresses a change to the Python
-    grammar in version 3.13.4 that made such a line break a syntax error.
+    Ruff will no longer activate deprecated rules selected by their group name
+    or prefix. As noted below, the two remaining deprecated rules were also
+    removed in this release, so this won't affect any current rules, but it will
+    still affect any deprecations in the future.
 
-- **`rust-toolchain.toml` is no longer included in source distributions**
+- **The deprecated macOS configuration directory fallback has been removed**
 
-    The `rust-toolchain.toml` is used to specify a higher Rust version than Ruff's
-    minimum supported Rust version (MSRV) for development and building release
-    artifacts. However, when present in source distributions, it would also cause
-    downstream package maintainers to pull in the same Rust toolchain, even if
-    their available toolchain was MSRV-compatible.
+    Ruff will no longer look for a user-level configuration file at
+    `~/Library/Application Support/ruff/ruff.toml` on macOS. This feature was
+    deprecated in v0.5 in favor of using the [XDG
+    specification](https://specifications.freedesktop.org/basedir-spec/latest/)
+    (usually resolving to `~/.config/ruff/ruff.toml`), like on Linux. The
+    fallback and accompanying deprecation warning have now been removed.

 The following behaviors have been stabilized:
 
-- [`collection-literal-concatenation`] (`RUF005`) now recognizes slices, in
-    addition to list literals and variables.
-- The fix for [`readlines-in-for`] (`FURB129`) is now marked as always safe.
-- [`if-else-block-instead-of-if-exp`] (`SIM108`) will now further simplify
-    expressions to use `or` instead of an `if` expression, where possible.
-- [`unused-noqa`] (`RUF100`) now checks for file-level `noqa` comments as well
-    as inline comments.
-- [`subprocess-without-shell-equals-true`] (`S603`) now accepts literal strings,
-    as well as lists and tuples of literal strings, as trusted input.
-- [`boolean-type-hint-positional-argument`] (`FBT001`) now applies to types that
-    include `bool`, like `bool | int` or `typing.Optional[bool]`, in addition to
-    plain `bool` annotations.
-- [`non-pep604-annotation-union`] (`UP007`) has now been split into two rules.
-    `UP007` now applies only to `typing.Union`, while
-    [`non-pep604-annotation-optional`] (`UP045`) checks for use of
-    `typing.Optional`. `UP045` has also been stabilized in this release, but you
-    may need to update existing `include`, `ignore`, or `noqa` settings to
-    accommodate this change.
+- [`assert-raises-exception`](https://docs.astral.sh/ruff/rules/assert-raises-exception) (`B017`)
+    now checks for direct calls to `unittest.TestCase.assert_raises` and `pytest.raises` instead of
+    only the context manager forms.

+    and [`prohibited-trailing-comma`](https://docs.astral.sh/ruff/rules/prohibited-trailing-comma)
+    (`COM819`) now check for trailing commas in PEP 695 type parameter lists.
+- [`raw-string-in-exception`](https://docs.astral.sh/ruff/rules/raw-string-in-exception) (`EM101`)
+    now also checks for byte strings in exception messages.
+- [`invalid-mock-access`](https://docs.astral.sh/ruff/rules/invalid-mock-access) (`PGH005`) now
+    checks for `AsyncMock` methods like `not_awaited` in addition to the synchronous variants.
+- [`useless-import-alias`](https://docs.astral.sh/ruff/rules/useless-import-alias) (`PLC0414`) no
+    longer applies to `__init__.py` files, where it conflicted with one of the suggested fixes for
+    [`unused-import`](https://docs.astral.sh/ruff/rules/unused-import) (`F401`).
+- [`bidirectional-unicode`](https://docs.astral.sh/ruff/rules/bidirectional-unicode) (`PLE2502`) now
+    also checks for U+061C (Arabic Letter Mark).
+- The fix for
+    [`multiple-with-statements`](https://docs.astral.sh/ruff/rules/multiple-with-statements)
+    (`SIM117`) is now marked as always safe.

+
+## 0.12.0
+
+Check out the [blog post](https://astral.sh/blog/ruff-v0.12.0) for a migration
+guide and overview of the changes!
+
+### Breaking changes
+
+- **Detection of more syntax errors**
+
+    Ruff now detects version-related syntax errors, such as the use of the `match`
+    statement on Python versions before 3.10, and syntax errors emitted by
+    CPython's compiler, such as irrefutable `match` patterns before the final
+    `case` arm.
+
+- **New default Python version handling for syntax errors**
+
+    Ruff will default to the *latest* supported Python version (3.13) when
+    checking for the version-related syntax errors mentioned above to prevent
+    false positives in projects without a Python version configured. The default
+    in all other cases, like applying lint rules, is unchanged and remains at the
+    minimum supported Python version (3.9).
+
+- **Updated f-string formatting**
+
+    Ruff now formats multi-line f-strings with format specifiers to avoid adding a
+    line break after the format specifier. This addresses a change to the Python
+    grammar in version 3.13.4 that made such a line break a syntax error.
+
+- **`rust-toolchain.toml` is no longer included in source distributions**
+
+    The `rust-toolchain.toml` is used to specify a higher Rust version than Ruff's
+    minimum supported Rust version (MSRV) for development and building release
+    artifacts. However, when present in source distributions, it would also cause
+    downstream package maintainers to pull in the same Rust toolchain, even if
+    their available toolchain was MSRV-compatible.
+
+### Removed Rules
+
+The following rules have been removed:
+
+- [`suspicious-xmle-tree-usage`](https://docs.astral.sh/ruff/rules/suspicious-xmle-tree-usage/)
+    (`S320`)
+
+### Deprecated Rules
+
+The following rules have been deprecated:
+
+- [`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name/)

+- [`private-type-parameter`](https://docs.astral.sh/ruff/rules/private-type-parameter) (`UP049`)
+
+The following behaviors have been stabilized:
+
+- [`collection-literal-concatenation`] (`RUF005`) now recognizes slices, in
+    addition to list literals and variables.
+- The fix for [`readlines-in-for`] (`FURB129`) is now marked as always safe.
+- [`if-else-block-instead-of-if-exp`] (`SIM108`) will now further simplify
+    expressions to use `or` instead of an `if` expression, where possible.
+- [`unused-noqa`] (`RUF100`) now checks for file-level `noqa` comments as well
+    as inline comments.
+- [`subprocess-without-shell-equals-true`] (`S603`) now accepts literal strings,
+    as well as lists and tuples of literal strings, as trusted input.
+- [`boolean-type-hint-positional-argument`] (`FBT001`) now applies to types that
+    include `bool`, like `bool | int` or `typing.Optional[bool]`, in addition to
+    plain `bool` annotations.
+- [`non-pep604-annotation-union`] (`UP007`) has now been split into two rules.
+    `UP007` now applies only to `typing.Union`, while
+    [`non-pep604-annotation-optional`] (`UP045`) checks for use of
+    `typing.Optional`. `UP045` has also been stabilized in this release, but you
+    may need to update existing `include`, `ignore`, or `noqa` settings to
+    accommodate this change.
+

They also increase the cognitive load of reading the code.\n\nIf an import statement is used to check for the availability or existence\nof a module, consider using `importlib.util.find_spec` instead.\n\nIf an import statement is used to re-export a symbol as part of a module's\npublic interface, consider using a \"redundant\" import alias, which\ninstructs Ruff (and other tools) to respect the re-export, and avoid\nmarking it as unused, as in:\n\n```python\nfrom module import member as member\n```\n\nAlternatively, you can use `__all__` to declare a symbol as part of the module's\ninterface, as in:\n\n```python\n# __init__.py\nimport some_module\n\n__all__ = [\"some_module\"]\n```\n\n## Fix safety\n\nFixes to remove unused imports are safe, except in `__init__.py` files.\n\nApplying fixes to `__init__.py` files is currently in preview. The fix offered depends on the\ntype of the unused import. Ruff will suggest a safe fix to export first-party imports with\neither a redundant alias or, if already present in the file, an `__all__` entry. If multiple\n`__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix\nto remove third-party and standard library imports -- the fix is unsafe because the module's\ninterface changes.\n\n## Example\n\n```python\nimport numpy as np  # unused import\n\n\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nUse instead:\n\n```python\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nTo check the availability of a module, use `importlib.util.find_spec`:\n\n```python\nfrom importlib.util import find_spec\n\nif find_spec(\"numpy\") is not None:\n    print(\"numpy is installed\")\nelse:\n    print(\"numpy is not installed\")\n```\n\n## Preview\nWhen [preview](https://docs.astral.sh/ruff/preview/) is enabled,\nthe criterion for determining whether an import is first-party\nis stricter, which could affect the suggested fix. See [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc) for more details.\n\n## Options\n- `lint.ignore-init-module-imports`\n- `lint.pyflakes.allowed-unused-imports`\n\n## References\n- [Python documentation: `import`](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement)\n- [Python documentation: `importlib.util.find_spec`](https://docs.python.org/3/library/importlib.html#importlib.util.find_spec)\n- [Typing documentation: interface conventions](https://typing.python.org/en/latest/spec/distributing.html#library-interface-public-and-private-symbols)\n"

They also increase the cognitive load of reading the code.\n\nIf an import statement is used to check for the availability or existence\nof a module, consider using `importlib.util.find_spec` instead.\n\nIf an import statement is used to re-export a symbol as part of a module's\npublic interface, consider using a \"redundant\" import alias, which\ninstructs Ruff (and other tools) to respect the re-export, and avoid\nmarking it as unused, as in:\n\n```python\nfrom module import member as member\n```\n\nAlternatively, you can use `__all__` to declare a symbol as part of the module's\ninterface, as in:\n\n```python\n# __init__.py\nimport some_module\n\n__all__ = [\"some_module\"]\n```\n\n## Fix safety\n\nFixes to remove unused imports are safe, except in `__init__.py` files.\n\nApplying fixes to `__init__.py` files is currently in preview. The fix offered depends on the\ntype of the unused import. Ruff will suggest a safe fix to export first-party imports with\neither a redundant alias or, if already present in the file, an `__all__` entry. If multiple\n`__all__` declarations are present, Ruff will not offer a fix.
