[frontier] Agent handoffs lose critical state or pass corrupted data between agents in swarms

Use strict input type validation and filtering in handoff definitions with Pydantic models to ensure state integrity during agent transfers

Journey Context:
In multi-agent swarms, handoffs often pass raw conversation history or unvalidated state dictionaries, leading to agents receiving malformed inputs, context window overflow from inherited history, or sensitive data leakage. The production pattern is to define explicit input schemas \(Pydantic models\) for each handoff that validate and filter the incoming state—dropping irrelevant message history, extracting only structured data fields, and type-checking all inputs. This treats handoffs like API boundaries with strict contracts rather than 'pass the blob' delegation.
