EchoScope 0.13.0 — airport approach radar

Airport selection now follows your overlay filters, with a close-up radar page for each airport.

• Nearby airports applies Airline/All and size filters before selecting the nearest nine matches. Overlay Off hides icons only; the airport list uses Airline mode with the saved size filter.
• Rotate to select an airport. The outer ring shows airports; < / > switches details and approach pages. Rotation preserves the page; centre tap/click returns to radar.
• North-up approach radar covers a 10 km radius around the airport, with actual runway endpoints where available and nearby aircraft/available trails from the current home feed.
• Runways are cached daily from OurAirports. Up to three longest open runways with valid endpoints are retained. Missing data uses a centre marker, without inventing runway alignment.
• Coverage/stale data is labelled. This is a proximity display using the existing approximately 100 km home feed, current type/altitude filters and 64-aircraft limit—not confirmed arrivals/departures. No extra aircraft polling is added.

Verified against current OurAirports data around 51.5, 0: Gatwick appears in the filtered list and supplies 08R/26L and 08L/26R runway coordinates. 45 service tests, Docker endpoint checks, native LVGL navigation/render checks and release firmware build passed. Device not flashed.

Update both Docker (git pull, make docker) and firmware (git pull, hold the knob for five seconds, make upload IP=192.168.2.151). Open Information → Nearby airports, then tap either side arrow for the approach view.
