Initial commit: Vigilar DIY home security system

Phase 1 (Foundation): project skeleton, TOML config + Pydantic validation,
MQTT bus wrapper, SQLite schema (9 tables), Click CLI, process supervisor.

Phase 2 (Camera): RTSP capture via OpenCV, MOG2 motion detection with
configurable sensitivity/zones, adaptive FPS recording (2fps idle/30fps
motion) via FFmpeg subprocess, HLS live streaming, pre-motion ring buffer.

Phase 3 (Web UI): Flask + Bootstrap 5 dark theme, 6 blueprints, Jinja2
templates (dashboard, kiosk 2x2 grid, events, sensors, recordings, settings),
PWA with service worker + Web Push, full admin settings UI with config
persistence.

Remote Access: WireGuard tunnel configs, nginx reverse proxy with HLS
caching + rate limiting, bandwidth-optimized remote HLS stream (426x240
@ 500kbps), DO droplet setup script, certbot TLS.

29 tests passing.
