feat: sysops_agent — Docker/git self-management with auto-heal

Adds a new specialist agent that gives the AI system control over its
own infrastructure:

- sysops_tools.py: docker SDK (ps/logs/restart) + git CLI (pull/status/log)
  + Odoo channel notifier for autonomous action broadcasts
- sysops_agent.py: BaseAgent subclass handling on-demand chat requests,
  auto_heal() triggered by health failures, and sweep() for audits
- Background auto-heal loop (main.py): runs every 2 minutes, calls
  _get_failing_systems() and triggers auto_heal() when degraded
- health.py: extracted _get_failing_systems() helper reused by both
  the /health/detailed endpoint and the auto-heal loop
- docker-compose.yml: mount docker socket + /root/odoo workspace +
  SSH keys for git authentication
- Dockerfile: add git to apt-get
- requirements.txt: add docker==7.1.0 Python SDK

Auto-heal behavior:
  - Detects failing containers, restarts them, notifies all bot DM channels
  - Ollama (192.168.2.9) is flagged as external and skipped
  - On-demand via chat: "restart agent", "check logs", "pull latest code"
