Initial commit: frigate-notify application

AI-powered video alert service that bridges Frigate NVR events to Matrix.
Listens to MQTT, uses Claude Haiku vision to analyze snapshots, and posts
annotated alerts to a Matrix room.

- app/main.py: MQTT subscriber and event orchestration loop
- app/vision.py: Claude Haiku vision analysis wrapper
- app/matrix_client.py: Matrix HTTP client for sending messages/images
- app/requirements.txt: Python dependencies
- Dockerfile: container image build definition
- docker-compose.yml: deployment configuration (host network, NAS mounts)
- .env.example: required environment variable template (copy to .env)
