AvianVisitors: BirdNET-Pi collage frontend overlay
Adds avian/ on top of upstream BirdNET-Pi: - frontend/ static collage UI (mask-packed bird tiles, sized by detection count) - assets/ ~450 bundled kachō-e illustrations + cutouts + binary masks - api/ PHP shims for recent/lifelist/firstseen/timeseries JSON - scripts/ installer + Gemini pregen + editable prompt template - caddy/ snippet mounting /collage on existing Caddy - forwarding/ optional HA / MQTT / Cloudflare configs Default install: http://birdnet.local/collage/ with no auth. Upstream BirdNET-Pi README preserved at README.upstream.md.
