Core type checking

• Added support for return type inference for unannotated functions and methods (#​29253).

  Return type inference is currently disabled by default. Enable it with the analysis.return-type-inference setting in pyproject.toml:

  [tool.ty.analysis]
  return-type-inference = "always"

  Or in ty.toml:

  [analysis]
  return-type-inference = "always"

  Please share your feedback, especially any problems you encounter, in the return type inference feedback issue.

• Report invalid Generic and Protocol arguments containing nested variadic type variables (#​29146)

Performance

• Speed up generic class-pattern narrowing by skipping impossible intersection comparisons (#​29240)
