Add containerized agent execution with Apple Container
- Agents run in isolated Linux VMs via Apple Container - All groups get Bash access (safe - sandboxed in container) - Browser automation via agent-browser + Chromium - Per-group configurable additional directory mounts - File-based IPC for messages and scheduled tasks - Container image with Node.js 22, Chromium, agent-browser Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
