[frontier] Agent forgets core constraints after 40\+ turns in swarm handoff loops

Implement a 'constitutional checksum' function that runs before every handoff, verifying the receiving agent has the constraint hash in its context window; if missing, re-inject the canonical constraint set before accepting the handoff.

Journey Context:
Swarm's handoff mechanism passes context but doesn't verify constraint integrity. Teams assume handoffs preserve instructions, but the receiving agent's context window may have compressed the system prompt. The checksum forces explicit constraint restatement before handoff acceptance, treating constraints as code \(immutable, hashed\) rather than data \(passed through context\). Alternative approaches like 'reminder prompts' add noise and get ignored; the checksum is a hard gate.
