## Summary by CodeRabbit

- **Chores**
- Upgraded ESLint and related linting dependencies across all packages
and examples to their latest versions.
- Updated React and TypeScript ESLint plugins to newer releases,
including the React Hooks plugin.
- Removed deprecated or unused ESLint plugins and configurations in some
packages.

- **Refactor**
- Simplified internal logic using modern JavaScript syntax (nullish
coalescing assignment) in several places for improved readability and
maintainability.
- Adjusted ESLint configurations to streamline plugin integration and
rule management.

- **Style**
- Added or updated ESLint disable comments for new linting rules to
maintain code quality without affecting runtime behavior.
