Claude caf117cf98 fix(java): resolve E.CONST.method() enum-constant receiver dispatch (#2561)
Calling a method on an enum-constant receiver (E.CONST.method()) emitted
no CALLS edge. The receiver "E.CONST" is a two-segment compound receiver;
resolveCompoundReceiverClass walks each dotted segment via the owning
class scope's typeBindings map, but enum constants had no typeBinding, so
the constant segment dead-ended and no target was ever resolved.

#2555/#2558 gave bodied constants a first-class synthesized E$N class with
an MRO that includes the host enum; this is the receiver-side follow-up.
synthesizeJavaAnonymousClassDeclarations now emits a class-scope
typeBinding for every enum constant's simple name -> its E$N class (bodied)
or the host enum itself (body-less), reusing the exact mechanism a field
declaration uses. The generic compound-receiver chain walk then resolves
E.CONST.method() with no change to any shared scope-resolution code.

Bodied dispatch (EnumConst.A.hook() -> EnumConst$1.hook#0) and body-less
inherited dispatch (Plain.A.m() -> Plain.m#0) are covered by new tests in
the existing java-enum-constant-body fixture; both were verified to fail
against the pre-fix tree.
