Implement Component 36: Guided Troubleshooting

Proactive contextual help that appears when users encounter problems,
but never when things are working well.

Trigger conditions:
- Detection quality drop: Zone-level quality below 60% for >24h
  triggers helpful banner with guided diagnostics flow
- Repeated setting changes: Same settings key modified 3+ times
  within 60-minute sliding window triggers helpful hint
- Node offline: Any node offline for >2 hours shows troubleshooting
- First-time feature discovery: Brief tooltip shown once per feature
- After false positive feedback: Inline response explaining adjustments
- After successful calibration: Positive reinforcement message

Implementation:
- ZoneQualityTracker: Tracks per-zone detection quality, triggers
  callbacks when quality degrades
- EditTracker: Monitors settings edits for repeated changes
- FleetNotifier: Tracks node offline events
- DiscoveryTracker: Manages first-time feature tooltips
- API endpoints: /api/guided/* for diagnostics and feedback
