Walkthrough

The change updates Kind::contains so typeMember conventions no longer match TypeScript type parameters. Type parameters remain matched by typeLike and typeParameter selectors. A regression test configures distinct naming formats for type members and type parameters. A patch changeset documents the fix for @biomejs/biome.

Merge Risk: ⚪ Minimal · up to 8f1b2

The selector now excludes type parameters from type-member conventions while retaining separate type-parameter matching, with regression coverage for distinct naming rules. No current merge-blocking risk is identified.
