Add event collector and MCP query tools

🗄️ New collector/ component:
- collector.py: FastAPI service receiving events from cameras
- SQLite database for event storage
- Snapshot images saved to disk by date
- launchd setup script for macOS

🔍 New MCP tools in vision_mcp.py:
- vision_get_events(): Query events with filters
- vision_get_event_snapshot(): View event image inline
- vision_annotate_event(): Add meaning + tags to events
- vision_event_stats(): Database statistics

📡 Complete flow:
Pi detects motion → POST to collector → stored in DB
Vixy queries events → views snapshots → annotates

Ready to deploy! 🦊
