[frontier] Agent loses accumulated session context and constraints when conversation is segmented or context window resets

Implement an identity handoff protocol: at each session boundary, the agent generates a structured summary capturing active constraints, task state, user-specific adaptations, and key decisions. This handoff document is injected as the first context in the new session segment, before the original system prompt.

Journey Context:
When conversations exceed context limits or are deliberately segmented, the agent loses both original constraints and session-learned adaptations \(e.g., 'this user prefers detailed explanations' or 'we decided to use library X instead of Y'\). Simply restarting with the original system prompt doesn't work because it discards session-specific learning that is crucial for task continuity. The identity handoff pattern preserves both original identity and accumulated context. The handoff document must be structured \(not freeform\) so the new session can parse it reliably. This is becoming standard practice for production agents operating over hours or days, and is being formalized in agent frameworks through state serialization and checkpointing mechanisms.
