Provides `dumps` (to JSON string) and `dumpd` (to dict) for serializing `Serializable` objects. ## Escaping During serialization, plain dicts (user data) that contain an `'lc'` key are escaped by wrapping them: `{"__lc_escaped__": {...original...}}`. This prevents injection attacks where malicious data could trick the deserializer into instantiating arbitrary classes. The escape marker is removed during deserialization. This is an allowlist approach: only dicts explicitly produced by `Serializable.to_json()` are treated as LC objects; everything else is escaped if it could be confused with the LC format.

Handles the special case where a `ChatGeneration` contains an `AIMessage` with a parsed Pydantic model in `additional_kwargs["parsed"]`.
