Adds the Seeed XIAO ESP32S3 Sense (ESP32-S3R8 with 8 MB octal PSRAM and 8 MB flash, with the Sense expansion board) to mooninstaller/deviceModels.json, on the esp32s3-n8r8 firmware. Picking it in the installer sets up:

• the PDM microphone on ws 42 and sd 41, at the default 24 kHz;
• the microSD slot over SPI: clk 7, MOSI 9, MISO 8, CS 21;
• the BOOT button (pin 0) toggling Control.switch1;
• the RMT LED driver, with its pins left to the user, as the Generic ESP32 Dev, LOLIN D32, LILYGO T7-S3 and ESP32-C3 SuperMini entries leave them.

The board has no antenna of its own, only a u.FL connector, so the description says WiFi needs the antenna attached.

The camera is listed under planned. I would like it to become a step in the "Video in, LED walls out" plan, behind the source registry; I will raise that separately.

What an agent wrote. Claude Opus 5.5 wrote the entry and this description from the board's schematics, arduino-esp32's pins_arduino.h and camera_pins.h, and Seeed's wiki; I reviewed every line.

Tested on two XIAO ESP32S3 Sense units with the Sense board attached, running esp32s3-n8r8 built from this tree:

• the entry's state applied over HTTP and read back, on both;
• the microphone with music playing, on both: gate open, 4 to 7 onsets a second;
• the microphone on the second unit with four test tones from a speaker (100 Hz, 1 kHz, 4 kHz, 9 kHz), at 16 and 24 kHz: both rates place the first three, 24 kHz places the 9 kHz tone in its top band where 16 kHz cannot, and the band analysis reports 9% CPU at 24 kHz against 6% at 16 kHz;
• the SD card, one 4 GB card moved between the units, mounted and listed on both, and a 35-byte file written, read back and deleted on the first;
• the BOOT button on the second unit: a press reached Control.switch1;
• a 24-LED WS2812B strip (GRB) on pin 1 of the second unit, set by hand as the entry leaves pins to the user, lit by the RMT driver with a sound-reactive effect;
• check_devices.py: 46 devices, 0 issues.

Not tested: a write over about 50 KB, the size at which an SPI card can stop until a power cycle, as the SD card service warns.

Tried and left out: s60sc's ESP32-CAM_MJPEG2SD drives this slot as SDMMC 1-bit on clk 7, cmd 9, d0 8, but MoonLight's SDMMC found no card on those pins (cause not traced), so the entry keeps SPI.

Reported by a user on the WLED Discord: the microphone works in MoonLight with PDM, ws 42 and sd 41, and he runs three curtains from pins 1, 2 and 4.

What changed in this PR

Adds the Seeed XIAO ESP32S3 Sense to MoonLight’s device catalog so the installer can select compatible firmware and configure its supported peripherals.

Changes:

• Selects esp32s3-n8r8 firmware and configures the PDM microphone, SPI microSD slot, and BOOT button toggle.
• Includes the RMT LED driver with user-selected pins.
• Documents the external antenna requirement and lists camera support as planned.

File	Description
mooninstaller/​deviceModels.json	Adds the board entry with firmware selection, peripheral defaults, and hardware notes.
