Phase 2: full LVGL face + Wi-Fi + gateway WebSocket + touch-to-talk

The device now runs the complete face contract on glass: seven states
with glyph expressions (custom 140px face font), matrix rain as pooled
label streams (22px DejaVu+Noto katakana font), rage kaomoji frames
(64px), orbit arc + elapsed counter wait cues, blink/talk/thought
animations, idle clock (SNTP, Europe/Amsterdam), and the power ladder
(active/ambient 35%/dormant 5% with rain parked).

Voice path: ES7210 mic capture task streams 16k PCM over
esp_websocket_client to the gateway; reply PCM buffers to PSRAM and
plays via the audio task; touch-to-talk (tap to speak, tap to send).
Protocol mapping per docs: thinking->effort, audio->speaking,
error event->rage (auto-composes after 2 loops), WS loss->error face.

Bring-up fixes: 8MB factory partition (fonts overflowed 1.5M),
bsp_display_lock(0) is try-lock in this adapter (use UINT32_MAX),
gong synth yields to feed IDLE0, wifi scan diagnostics (found SSID
case mismatch), esp_websocket_client pinned ~1.3 (1.4 needs IDF>5.5).

Verified on hardware: boots, connects to Wi-Fi and holds an open
WebSocket to the gateway. Sauron (iMac TTY endpoint + ops console)
planned in architecture.md.

 ## Roadmap
 
-1. **Bring-up** — ESP-IDF toolchain, build/flash, BSP display + Wi-Fi working
-2. **Face** — LVGL face with idle/listening/thinking/speaking states, clock while idle
+1. ~~**Bring-up**~~ ✅ — display, touch, audio, 200 MHz PSRAM, cathedral gong
+2. **Face + voice loop** (in hardware test) — full LVGL face (7 states, rain, orbit, power ladder), Wi-Fi, WebSocket, touch-to-talk
 3. **Voice (touch-to-talk)** — tap to talk → gateway → Tatlock → spoken reply
 4. **Wake word** — esp-sr WakeNet on-device, echo cancellation, barge-in
 5. **Polish** — Tatlock-initiated notifications, presence, OTA updates
