chore: add husky pre-commit hook and auto-fix lint warnings

- Install husky for git hooks
- Add pre-commit hook to run 'npm run lint -- --fix' before each commit
- Auto-fix 6 additional warnings (attribute order, escape chars)
- 0 errors, 208 warnings (down from 214)

This ensures code quality checks run automatically before commits.
