Hi All,

I’ve pushed an update addressing the feedback:

- Moved the suppression guard into the case AR_Deprecated: block
-  Used dyn_cast_if_present<CXXMethodDecl> and combined isImplicit()/isDefaulted() in one check
-  Consolidated constructor/destructor detection with isa<CXXConstructorDecl, CXXDestructorDecl>
-  Removed the FunctionDeck typo—now correctly casting to CXXMethodDecl
-  Dropped the PR number from the release notes entry

All Sema tests (check-clang)pass locally. Please take another look when you have a moment, and let me know if there’s anything else I can improve!

Thank you for your guidance,
Shashi
