Expose active SET DEFAULT operations through AlterExpression.getColumnDefaults() and ColumnDefaultAction. Consumers can inspect and mutate the same existing AST objects for tables and views. Value rendering is shared, including opaque legacy String values and custom expression printers. Constraint actions suppress inactive defaults in both access and deparsing.

Existing parser result classes and public method signatures are retained. This change does not expand grammar or dialect acceptance.

Validation: 273 focused tests pass for the initial API; 293 tests pass after the active-state fix. Spotless passed. usage.rst includes a usage example.

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.
