Summary

Improve attrs support in the ty type checker by defining the slots_default parameter of the dataclass_transform decorator.

xref:

• ty 0.0.83 breaks overriding of attrs abstract properties astral-sh/ty#4591
• [ty] Support slots_default in dataclass_transform astral-sh/ruff#28885

Also bumped the ty version in the lockfile to a version that has the linked PR, and the pyrefly version // removed the UV exclusion.

I haven't added a changelog entry as this is a pure stubs-only change, but happy to do so if you'd like!
