Phase 3f complete: Advanced Memory Management (Steps 64-67)

Step 64: AnnotationValidator — @Deallocate missing-intent, @Owner(Single) alias detection, parent/child conflict (5/5 tests)
Step 65: MemoryStrategyInference — language defaults, per-function pattern analysis, confidence scores (5/5 tests)
Step 66: CrossLanguageProjector — deep-copy AST projection, annotation-aware CppGenerator (shared_ptr/unique_ptr) (5/5 tests)
Step 67: Optimization annotations — HotCold, Inline, Pure, ConstExpr with C++ attribute generation (9/9 tests)
