Autonomous systems: watchdog, smart deploy, site health, auto-heal, agent installer

- deploy/jarvis-watchdog.sh: self-healing watchdog (every 5 min)
  * monitors lsws/mysql/redis, restarts on failure
  * JARVIS HTTP self-check, restarts OLS on 5xx
  * disk/memory alerts inserted to DB
  * offline Proxmox VM agents restarted via qm guest exec
  * log rotation (1000 line cap)
- deploy/jarvis-deploy.sh: smart deploy with PHP validation
  * php8.3 syntax check on every changed .php file
  * auto-reverts git commit + inserts critical alert on syntax error
  * reloads OLS after JARVIS deploys
- api/endpoints/facts_collector.php: site health monitoring
  * curls all 7 managed sites every 3 min
  * stores up/down status in kb_facts
- api/endpoints/alerts.php: auto-heal + site alerts
  * dispatches restart_service commands when services down on agents
  * generates alerts from kb_facts site health data
- public_html/install-agent.sh: one-liner Linux agent installer
  * installs deps, downloads agent, registers with JARVIS, sets up systemd
- public_html/webhook.php: fixed infra deploy path to /opt/infra
