Abhijeet Prasad Bodas 68b0386007 [ty] Implement DataClassInstance protocol for dataclasses. (#18018) ... Fixes: https://github.com/astral-sh/ty/issues/92 ## Summary We currently get a `invalid-argument-type` error when using `dataclass.fields` on a dataclass, because we do not synthesize the `__dataclass_fields__` member. This PR fixes this diagnostic. Note that we do not yet model the `Field` type correctly. After that is done, we can assign a more precise `tuple[Field, ...]` type to this new member. ## Test Plan New mdtest. --------- Co-authored-by: David Peter <mail@david-peter.de>		2025-05-13 10:31:26 +02:00
