C5->E5 half-second chime with fade-out at boot, right after the face renders. Codec opens in slave mode, esp_codec_dev write path works. Phase 1 bring-up is now complete: display, touch, audio, 200MHz PSRAM. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* DeskLock — living-room face and voice for the Tatlock butler.

*
|
|
* Boot sequence (planned):
|
|
* 1. BSP init: display + LVGL, touch, audio codec (ES8311/ES7210)
|
|
* 2. Wi-Fi up via ESP32-C6 (ESP-Hosted over SDIO)
|
|
* 3. WebSocket connection to the DeskLock gateway
|
|
* 4. Face state machine: idle / listening / thinking / speaking
|
|
*
|
|
* Current stage: bring-up — display + a placeholder face.
