JakubandClaude Opus 5.5 331a4e64c4 feat(l2): Arduino-ESP32 3.3.12 / IDF 5.5 env, NimBLE and new I2S driver ports, large UI buffers in PSRAM 
- New env Wio_Tracker_L2_companion_solo_lvgl_v3 on pioarduino 55.03.312-1;
  the 2.0.17 env stays until the new one passes the hardware checklist
- SerialBLEInterface: NimBLE variant (PIN pairing through encrypted,
  authenticated characteristic properties; setAccessPermissions is a no-op)
- buzzer: i2s_std driver on IDF 5 (legacy driver kept for 2.0.17)
- ESPNOWRadio: IDF 5 callback signatures
- ui-lvgl: psramBuf() for trail drawing, tile cache, map marks, list rows,
  keyboard maps and message metadata; internal heap back to 2.0.17 level

// Navigation map (Home > Map): one of the map screen's two modes. It shows only
// what you navigate by: saved waypoints, people sharing their position live,
// the recorded trail, and the Locator's active target with a line to it and a
// bar with distance, bearing, course and ETA. The Nodes map (Nearby > map
// button) is the one with every contact.
//
// Everything shown lives in the UI Core (waypoints, locator target, live
// shares, trail), so ui-new's Trail / Waypoints / Locator screens and this map
// work on the same data. Here: the pin button opens the waypoint list (add at
// the GPS position or by coordinates; tap one for its menu: navigate, rename,
// share, delete), a long-press on the map offers that spot as a waypoint or a
// target, the bar opens the target list.
