[ty] Add new unused-type-ignore-comment rule by MichaReiser · Pull Request #22790 · astral-sh/ruff (original) (raw)

Summary

This PR splits the unused-ignore-comment into two rules:

• unused-ignore-comment same as today, but it now only reports unused ty: ignore comments
• unused-type-ignore-comment: New, reports unused type: ignore comment

The separation allows projects using multiple type checkers to disable unused-type-ignore-comments
so that ty doesn't complain about type: ignore directies that are needed by another type checker.
But they can still use unused-ignore-comments to be warned about unused ty: ignore comments.

Fixes astral-sh/ty#2494
