docs(cpp,cuda): document pointer/reference declarator scope in handleDeclaration

Add an inline comment in handleCppDeclaration and handleCudaDeclaration
explaining that pointer_declarator / reference_declarator children are
intentionally skipped. Native Rust match_c_family_type_map has the same
scope: it only iterates 'init_declarator' and 'identifier' children, so
both engines behave identically for pointer/reference-typed locals.
