v3.8.0: AI Monitoring — self-healing watchdog with 3-tier response system

- HealthWatcher thread: monitors proxy /health every 5s
- LogAnalyzer thread: tails cc-debug.log for 18 failure signal patterns
- Tier 1 rule engine: 14 rules for instant auto-recovery (< 1s)
- Tier 2 incident store: JSON pattern database with success rates
- Tier 3 AI diagnostic agent: calls configurable provider/model for novel failures
- AIMonitoringWindow GUI: ON/OFF toggle, provider/model/API key selector, incident log
- 30 fault types catalogued across 5 categories (A-E)
- Enhanced /health endpoint with memory_mb, uptime_s, requests_total
- Auto-restart proxy, auto-clear schema cache, kill stale processes
- Safety: rate-limited AI calls, restart caps, cooldowns per pattern
- AI Monitoring design spec (AI-MONITORING-DESIGN.md)
- 54 self-test patterns passing
