Breaking changes

• ty now prefers the declared type of an annotated assignment in more situations (#​24802).
  Consider this example:

  from some_library import untyped_function
  
  threshold: int | None = 0
  result: str = untyped_function()

  ty previously favored the inferred type of the right hand side expression when threshold and result were used. This is useful for threshold, as it allows something like threshold += 1 to work without an error: we know that threshold could later become None, but right now, we see that it is an int. However, for result, the inferred type is Unknown. This is not a useful type and it can lead to false negatives. Starting with this release, ty will therefore prefer
  the declared type if the inferred and declared types are mutually assignable. In the above example, threshold will still be inferred as int (or rather Literal[1]), but result will now be inferred as str. If you previously added casts to work around this behavior, you should be able to remove them after upgrading.
