ash 62d1e430d5 Switch from NimBLE-Arduino to ESP32-BLE-MIDI library 
Replace direct NimBLE-Arduino dependency with max22/ESP32-BLE-MIDI
wrapper library (v0.3.2). Rewrite ble_midi_transport to use
BLEMidiServer API instead of raw NimBLEDevice calls.

Removes patch_nimble_device() from pre_build.py — no longer needed
since BT controller init is managed by the library internally.

The library uses NimBLE v1.4.1 internally and configures advertising
without setScanResponse() or setName(), which may resolve the invisible
BLE advertising issue on ESP32-S3.

ash 07e5cd8994 Rewrite MUX: WS2812C LEDs (NeoPixel) + 74HC165 buttons 
PixelStomp MUX uses:
- WS2812C LEDs: one data line via DAT (GPIO 9), NeoPixel protocol
- 74HC165 shift register: LD/CLK/DI for reading 8 button states

Changes:
- Use Adafruit NeoPixel library for LED control
- Proper 74HC165 parallel-load shift-in for buttons
- 8 switches + 8 LEDs (was incorrectly 10)
- Diagnostic commands: dump, ledtest, red, green, blue, read
