Replace the heartbeat-only Kimi snippet with a complete bridge script:
- Registers workspace in poll mode (NAT-safe, no public URL)
- Heartbeats every 20s to stay online
- Polls /workspaces/:id/activity every 5s for new canvas messages
- Extracts user text from request_body (A2A JSON-RPC envelope)
- Echo-replies via POST /workspaces/:id/notify
- Includes a one-off curl example for manual replies
The script is self-contained: operators paste it once, edit the reply
logic if desired, and run it in a background terminal. This gives Kimi
push parity with Claude Code / Hermes channel tabs for laptop/NAT
setups without requiring ngrok or Cloudflare Tunnel.
Modal label updated to reflect the new capabilities.
