Pull request overview

This PR graduates Groovy's sealed types feature from incubating to stable. It removes @Incubating annotations from the @Sealed/@NonSealed/@SealedOptions API and from ClassNode.isSealed/getPermittedSubclasses/setPermittedSubclasses, drops the "(incubating)" tag from the docs, and—more substantively—teaches the joint-compilation stub generator to emit native sealed/non-sealed/permits declarations so Java sources can correctly extend Groovy sealed types under JDK17+. Several new helper APIs are added to SealedASTTransformation to support phase-independent queries from the stub generator. Test coverage is reorganized: Groovy11292 is folded into a new SealedJointCompilationTest, and SealedTransformTest is extended with restricted-identifier, implicit-non-sealed, anonymous-class, coercion, retention, and @Delegate-interaction tests.

Changes:

• Strip @Incubating from sealed-related public API and update spec doc (also fixes a copy-paste mention of "record").
• Add wouldBeNativeSealed, getDeclaredPermittedSubclasses, getEffectivePermittedSubclasses, sealedSkipAnnotationFromSource in SealedASTTransformation and use them from JavaStubGenerator to emit sealed/non-sealed/permits and to suppress source-only sealed annotations.
• Add SealedJointCompilationTest (consolidating/expanding Groovy11292) and new GEP-13 conformance tests in SealedTransformTest; minor comment fix in Delegate.java.
