chore(ci): enforce pre-commit checks and remove auto-fix (#363)

Changed the GitHub Actions workflow to fail on pre-commit hook errors
instead of continuing, ensuring issues must be resolved manually before
proceeding. Removed automatic commit and push of pre-commit fixes to
maintain intentional code changes.
