- Fix infinite hang on mutually recursive TypeAliasType definitions (#23397)
LSP server

Core type checking
- Fix assignability, subtyping and equivalence checks relating to typing.Generator prior to Python 3.13 (#23386)
- Understand that a scope's control flow terminates after await foo() if foo returns typing.Awaitable[typing.Never] or similar (#23479)
- Implement stricter handling of calls to instances of type[T] types (#23472)
- Support basic type narrowing for case {...}: patterns in match statements (#23462)
- Fix bugs that could manifest in incorrect overload evaluation, false-positive complaints regarding assert_type calls or false-positive redundant-cast diagnostics by reimplementing the equivalence type relation as mutual subtyping of top and bottom materializations (#23428)
