Host-mode runner has no Node.js so JS composite actions fail.
All steps are now plain shell — git clone for checkout, docker
CLI for build/push. Zero external action dependencies.

The previous workflow ran jobs inside node:20-bookworm which has no
Docker CLI. Re-mapped label to :host and replaced composite actions
with direct docker build/push shell commands.

Server geolocates each egg by IP on first contact (ip-api.com), snaps
coordinates to the nearest 1-degree grid (~111 km) and adds a small
deterministic per-egg jitter so eggs in the same cell don't overlap.
Only country + rounded lat/lon are stored; exact IPs are never saved.
Front-end uses Leaflet with CartoDB dark tiles. Markers update on every
poll cycle and are coloured to match the current coherence index.
