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)

 // Step 64 TDD Test: Memory annotation validation
 //
 // Tests validation of canonical memory annotations:
-// 1. @Owner(Single) on aliased variable → error
+// 1. Valid @Reclaim(Tracing) passes
 // 2. @Deallocate(Explicit) without deallocation point → "Missing Intent" error
-// 3. Conflicting parent/child annotations → error
-// 4. Valid annotations pass without errors
-// 5. @Reclaim(Tracing) on @Policy(Perf: Critical) → warning
-//
-// Will fail until memory annotation validation is implemented.
+// 3. @Owner(Single) on aliased variable → error
+// 4. Conflicting parent/child annotations → error
+// 5. Valid @Lifetime(RAII) passes
