CWE: CWE-693
Resolve ct_eq to the constant-time trait call.
Both branches match the ct_eq identifier only. An unrelated method or bare path can therefore make constantTimeEq succeed and suppress the variable-time equality result. Match an invocation whose getResolvedTarget() resolves to subtle::ConstantTimeEq::ct_eq. Add regression coverage for unrelated paths and bare references.
