[ty] Default specialize generic type aliases

[ty] Don't confuse multiple occurrences of typing.Self when binding bound methods (#21754 )
In the following example, there are two occurrences of `typing.Self`, one for `Foo.foo` and one for `Bar.bar`: ```py from typing import Self, reveal_type class Foo[T]: def foo(self: Self) -> T: raise NotImplementedError class Bar: def bar(self: Self, x: Foo[Self]): # SHOULD BE: bound method Foo[Self@bar].foo() -> Self@bar # revealed: bound method Foo[Self@bar].foo() -> Foo[Self@bar] reveal_type(x.foo) def f[U: Bar](x: Foo[U]): # revealed: bound method Foo[U@f].foo() -> U@f reveal_type(x.foo) ``` When accessing a bound method, we replace any occurrences of `Self` with the bound `self` type. We were doing this correctly for the second reveal. We would first apply the specialization, getting `(self: Self@foo) -> U@F` as the signature of `x.foo`. We would then bind the `self` parameter, substituting `Self@foo` with `Foo[U@F]` as part of that. The return type was already specialized to `U@F`, so that substitution had no further affect on the type that we revealed. In the first reveal, we would follow the same process, but we confused the two occurrences of `Self`. We would first apply the specialization, getting `(self: Self@foo) -> Self@bar` as the method signature. We would then try to bind the `self` parameter, substituting `Self@foo` with `Foo[Self@bar]`. However, because we didn't distinguish the two separate `Self`s, and applied the substitution to the return type as well as to the `self` parameter. The fix is to track which particular `Self` we're trying to substitute when applying the type mapping. Fixes https://github.com/astral-sh/ty/issues/1713

+/// ## What it does
+/// Detects class `@property` methods that does not have a `return` statement.
+///
+/// ## Why is this bad?
+/// Property methods are expected to return a computed value, a missing return in a property usually indicates an implementation mistake.
+///
+/// ## Example
+/// ```python
+/// class User:
+///     @property
+///     def full_name(self):
+///         f"{self.first_name} {self.last_name}"
+/// ```
+///
+/// Use instead:
+/// ```python
+/// class User:
+///     @property
+///     def full_name(self):
+///         return f"{self.first_name} {self.last_name}"

+Checks for type alias definitions that (directly or mutually) refer to themselves.

+Although it is permitted to define a recursive type alias, it is not meaningful
+to have a type alias whose expansion can only result in itself, and is therefore not allowed.

+**Why is this bad?**

 be avoided wherever possible. As part of this check, therefore, ty enforces that `__eq__`
 and `__ne__` methods accept `object` as their second argument.

+**Why does ty disagree with Ruff about how to write my method?**
+
+
+Ruff has several rules that will encourage you to rename a parameter, or change its type
+signature, if it thinks you're falling into a certain anti-pattern. For example, Ruff's
+[ARG002](https://docs.astral.sh/ruff/rules/unused-method-argument/) rule recommends that an
+unused parameter should either be removed or renamed to start with `_`. Applying either of
+these suggestions can cause ty to start reporting an `invalid-method-override` error if
+the function in question is a method on a subclass that overrides a method on a superclass,
+and the change would cause the subclass method to no longer accept all argument combinations
+that the superclass method accepts.
+
+This can usually be resolved by adding [`@typing.override`][override] to your method
+definition. Ruff knows that a method decorated with `@typing.override` is intended to
+override a method by the same name on a superclass, and avoids reporting rules like ARG002
+for such methods; it knows that the changes recommended by ARG002 would violate the Liskov
+Substitution Principle.
+
+Correct use of `@override` is enforced by ty's `invalid-explicit-override` rule.

+
+
+**What it does**
+
+Checks for invalid type arguments in explicit type specialization.
+
+**Why is this bad?**
+
+Providing the wrong number of type arguments or type arguments that don't
+satisfy the type variable's bounds or constraints will lead to incorrect
+type inference and may indicate a misunderstanding of the generic type's
+interface.
+
+**Examples**
+
+
+Using legacy type variables:
+```python
+from typing import Generic, TypeVar
+
+T1 = TypeVar('T1', int, str)
+T2 = TypeVar('T2', bound=int)
+
+class Foo1(Generic[T1]): ...
+class Foo2(Generic[T2]): ...
+
+Foo1[bytes]  # error: bytes does not satisfy T1's constraints
+Foo2[str]  # error: str does not satisfy T2's bound
+```
+
+Using PEP 695 type variables:
+```python
+class Foo[T]: ...
+class Bar[T, U]: ...
+
+Foo[int, str]  # error: too many arguments
+Bar[int]  # error: too few arguments
+```

+**What it does**
+
