Pull Request Overview

This PR adds strict presets to the react-x and react-dom ESLint plugins, providing more stringent rule configurations beyond the existing recommended presets. The changes reorganize the plugin configurations by extracting TypeScript-specific and type-checking rules into separate modules and introducing new strict configuration variants.

Key changes:

• Introduction of strict configuration presets for both react-x and react-dom plugins
• Refactoring of TypeScript and type-checking rules into dedicated modules (_ts.ts, _tc.ts)
• Migration of certain rules from recommended to strict configurations to maintain backward compatibility
