feat(l2): Arduino 3.x as the published env, limits sized for the PSRAM, stage 7 findings

Browse Source 
- Wio_Tracker_L2_companion_solo_lvgl now builds on Arduino-ESP32 3.3.12
  (pioarduino); the 2.0.17 build stays as _solo_lvgl_arduino2 (not published)
- Per-board limits (defaults unchanged, L1 byte-for-byte the same):
  TRAIL_CAPACITY, WAYPOINT_CAPACITY, HIST_CH_MAX / HIST_DM_MAX, NEARBY_MAX;
  the L2 sets 4096 / 64 / 256 / 128 / 64 (in PSRAM with UiCore; internal
  heap 154 KB free after). ui-lvgl: 32 trail segments, contact list 256,
  rooms 32, 50 bubbles per conversation, pickers 128, WiFi scan 20
- Map trail drawing drops points under 2 px apart
- "Nearby" is "Nodes"; advert options "Zero hop" / "Flood"
- Roadmap stage 7: LVGL on other displays -- e-ink stays ui-new, an OLED
  spike after this roadmap, Cardputer as a colour candidate

Env `Wio_Tracker_L2_companion_solo_lvgl_v3` (flash with `L2_ENV=Wio_Tracker_L2_companion_solo_lvgl_v3`). Bluetooth runs on NimBLE now, the speaker on the new I2S driver. Internal heap at runtime: 147.9 KB free on 3.x vs 147.8 KB on 2.0.17 (large UI buffers moved to PSRAM; static RAM 109 → 71 KB).

- [ ] Boots, screen and touch as before; WAKE and USER buttons
- [ ] Bluetooth: the app pairs with the PIN (asks for it: the link is encrypted), connects, syncs contacts and messages, sends; reconnects after the app is closed / reopened; the Bluetooth switch still works
- [ ] Sound: startup chime, message sounds, melody editor, volume; no new knocks

- [ ] Map download popup: no WiFi button, fits the screen (scrolls if the unfinished-job row is shown); no network saved → toast pointing to Settings > WiFi
- [ ] Unlock (slider or right PIN): the lock fades away while the screen underneath drifts up into place, no instant jump
- [ ] Lock slider: knob snaps to the end near it but only unlocks on letting go; let go earlier → it springs back smoothly
## Roadmap stage 2: limits for the PSRAM (2026-09-26)
- [ ] Boot with `-D UI_HEAP_REPORT`: internal heap free still ~145 KB+ (the bigger rings go to PSRAM)
- [ ] Long walk / drive with the trail on: well past 512 points, the map stays smooth zoomed out, saving and GPX export work
- [ ] Waypoints: more than 16 can be added; the full message says (64)
- [ ] Busy channels: a conversation shows up to 50 bubbles, older ones are kept longer than before
- [ ] Nearby with many nodes: up to 64 rows; contact list "All" shows beyond 64 contacts
- [ ] Home tile and screen title read "Nodes" (was "Nearby")
- [ ] Nodes > advert: "Zero hop" / "Flood" (were "Nearby only" / "Everyone"), toasts "Zero-hop advert sent" / "Flood advert sent"
