## Summary Even disambiguating classes using their fully qualified names is not enough for some diagnostics. We've seen real-world examples in the ecosystem (and https://github.com/astral-sh/ruff/pull/20368 introduces some more!) where two types can be different, but can still have the same fully qualified name. In these cases, our disambiguation machinery needs to print the file path and line number of the class in order to disambiguate classes with similar names in our diagnostics. Helps with https://github.com/astral-sh/ty/issues/1306 ## Test Plan Mdtests
Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/ty_test/README.md for documentation of this test format.
