Added unsafe PyYAML loaders and other third-party deserialization functions (`shelve`, `dill`, `joblib`, `torch`, `numpy`) to `_SERIALISATION_SINKS` to ensure the taint engine correctly tracks untrusted data flowing into these endpoints. Updated tests and golden identities to reflect these changes.
