Reuse existing protected renderers from the stateless DROP and RENAME subclasses. Legacy AlterExpression construction now preserves RENAME AS and bare RENAME as parsed actions already do. The initial production change removes 29 net lines without deleting public or protected APIs.
Existing parser result classes and public method signatures are retained. This change does not expand grammar or dialect acceptance.
Validation: New tests reproduce two failures on the base for AS and bare RENAME. All 254 focused tests pass, plus Spotless, Checkstyle, PMD and SpotBugs.
Combined validation with the six related DDL refactoring branches: Gradle check passes (9,395 tests: 9,370 passed, 25 skipped, zero failures). Of 840 DDL cases accepted by MySQL 8.4.11/PostgreSQL 18.6, 835 parse and produce toString/deparser SQL that also executes successfully; the remaining 5 already fail to parse on base 87e8814. Final SQL outputs match the DB-replayed outputs exactly. These combined checks supplement the branch-specific tests above.
