Note: 7.1.0 accidentally removed the component-hook-factories rule, causing errors for users who referenced it in their ESLint config. This is now fixed.

• Add deprecated no-op component-hook-factories rule for backwards compatibility. (@mofeiZ in #36307)

This release adds ESLint v10 support, improves performance by skipping compilation for non-React files, and includes compiler lint improvements including better set-state-in-effect detection, improved ref validation, and more helpful error reporting.
