AI Summary

This release fixes critical sensing bugs on ESP32-S3 hardware, specifically addressing display initialization issues on bare boards and false detection of mmWave sensors via UART probing.

Key Highlights

  • Fixed CSI starvation on display-less DevKits by gating panel init with a touch controller readback.
  • Fixed false MR60BHA2 sensor detection in UART probing to prevent ENOMEM errors.
  • Validated fixes on real hardware (ESP32-S3 QFN56 rev v0.2).

Full Release Notes

ESP32-S3 CSI node firmware — two field-reported sensing bugs fixed and **validated on real hardware** (ESP32-S3 QFN56 rev v0.2, 8MB flash / 2MB PSRAM).

## Fixes
- **#1000 — no CSI on a bare/display-less DevKit.** The SH8601 QSPI AMOLED is write-only, so panel init "succeeds" even with no panel attached; that false-positive left `display_is_active()` true and starved CSI at MGMT-only frames. Now the readable FT3168 touch controller gates it: no touch readback → run headless → CSI upgrades to **MGMT+DATA**. (PR #1121)
- **#1107 — false MR60BHA2 detection → ENOMEM.** UART probe now requires a validated MR60 header (8-byte SOF + checksum + type `0x0A__`/`0x0F09`) instead of counting bare `0x01` bytes, so an empty UART no longer false-detects a sensor. (PR #1119)

## Hardware validation (boot log, rev v0.2 silicon)
```
disp_hal: SH8601 panel init OK (368x448)            # write-only panel "succeeds" on bare board
disp_hal: FT3168 not found (ret=ESP_FAIL)           # touch readback fails — no real panel
disp_task: ... running headless so CSI captures (#1000)
csi_collector: CSI filter upgraded to MGMT+DATA (no display, RuView#893)
mmwave: No mmWave sensor detected (CSI-only mode)   # no false detect on empty UART
```
CSI streamed cleanly (frames len 128→384/256), 600 callbacks / 22s, zero crash or watchdog.

## Flashing
ESP32-S3, esptool offsets:
```
esptool --chip esp32s3 -p <PORT> -b 460800 write_flash \
