Heartbeat Mcpl

Periodic self-wake MCPL server for Connectome agents.

On a configurable interval, sends a push/event (featureSet heartbeat, origin.source: heartbeat) to wake the agent for a self-check-in. The agent itself configures its own schedule via three MCP tools:

• heartbeat_status — show current interval, paused state, time-to-next, message
• heartbeat_configure — set intervalSeconds | intervalMinutes | intervalHours, paused, message; persists across restarts
• heartbeat_trigger — fire one heartbeat now (test/debug)

Schedule is persisted to ${HEARTBEAT_CONFIG_FILE:-./heartbeat-config.json}.

          "behavior": "always" }
        // ... your other policies after
      ]
    }
  }
}

The wake policy MUST come before any policy that would skip mcpl:push-events (e.g. a discord-ambient skip rule), since the gate is first-match-wins.
