GROOVY-12105: Unqualified super.m(...) from a static trait method thr…

…ows MissingMethodException — should be a compile error

[Copilot]

Pull request overview

This PR addresses GROOVY-12105 by turning an unqualified super.m(...) call from within a static trait method into a compile-time error (instead of compiling and later failing at runtime with MissingMethodException), while keeping the explicit T.super.m(...) form supported.

Changes:

• Add a new compile-time diagnostic in TraitReceiverTransformer to reject unqualified super usage in static trait method bodies.
• Add focused regression tests in a new Groovy12105.groovy test class and promote matrix row 15 from @NotYetImplemented to an enforced compile error expectation.
• Update matrix documentation/comments to reference GROOVY-12105 and point to the focused regression test.

File	Description
src/test/groovy/org/codehaus/groovy/transform/traitx/TraitStaticDispatchMatrix.groovy	Enables row 15 as an active compile-error expectation for unqualified super in static trait methods.
src/test/groovy/org/codehaus/groovy/transform/traitx/Groovy12105.groovy	Adds focused regression coverage for the new compile-time rejection and ensures T.super still works.
src/main/java/org/codehaus/groovy/transform/trait/TraitReceiverTransformer.java	Implements the compile-time rejection heuristic and emits a SyntaxException with guidance toward T.super.m(...).
