feat: add ESLint and Prettier with pre-commit hook

- Install ESLint 9 with TypeScript and React support
- Install Prettier with custom configuration (no semicolons)
- Add husky and lint-staged for pre-commit hooks
- Configure lint-staged to auto-fix and format on commit
- Relax ESLint rules to avoid large-scale code changes
- Format all existing code with Prettier (no semicolons)
