Critical fixes: - Wire monitor subsystem to agent startup (was dead code) - Implement NodeStatus RPC (disk, memory, CPU, runtime version, uptime) - Deploy respects active=false (sets desired_state=stopped, not always running) Medium fixes: - Add Started field to runtime.ContainerInfo, populate from podman inspect - Populate ComponentInfo.started in status handlers for uptime display - Add Monitor field to Agent struct for graceful shutdown Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
