CLI 0.21.0 — More agent turns survive API restarts

Hermes and OpenClaw turns can keep their upstream process and stream alive in the daemon while the Manyfold API restarts.

Highlights

• Daemon-owned turn transport. The daemon journals frames to its durable exec buffer while the API reads and replays them.
• Positive completion evidence. Recovery marks a turn complete only after the framework supplies its real end signal; ambiguous streams stay retryable.
• Faster runner presence. The daemon connects its WebSocket before slow framework probes, reducing false offline timeouts.
• Earlier Hermes validation. A missing primary model is rejected during creation instead of producing an unusable agent.
