Closes #

Follow up to #8143.

This PR enables React Compiler support for the shared hook internals in @primer/react. These hooks were still on the migration list because they needed small refactors to avoid compiler skips and keep callback/state behavior stable under compilation.

Changelog

New

Changed

• Update shared hook internals so they pass the React Compiler migration check.
• Add a patch changeset for enabling React Compiler support for shared hook internals.

Removed

Rollout strategy

• Patch release
• Minor release
• Major release; if selected, include a written rollout or migration plan
• None; if selected, include a brief description as to why

This should be a patch since it improves internal rendering behavior for existing hooks without changing the public API.

Testing & Reviewing

• npm run lint:react-compiler -w @primer/react

Would love a close look at the hook behavior changes, especially around callback stability and cleanup behavior.
