d23f5f00 - Fix false positive "Expected TypedDict key to be string literal" for Union[TypedDict, dict[K, V]] (#21511)

Fix false positive "Expected TypedDict key to be string literal" for Union[TypedDict, dict[K, V]] (#21511) When a variable is typed as `Union[TypedDict, dict[int, float]]`, mypy incorrectly raised `Expected TypedDict key to be string literal` when assigning a dict literal with non-string keys like `{1: 5.2}`. The plain `dict[int, float]` alternative makes the assignment valid, so this was a false positive. The root cause was that `match_typeddict_call_with_dict`, which is used as a probe to check whether a dict literal could match a TypedDict, was emitting errors from `validate_typeddict_kwargs` during the matching phase rather than silently returning `False`. Wrapping the call in `filter_errors()` suppresses those spurious diagnostics. Fixes #21510 Co-authored-by: Claude Agent <agent@example.com>
