Adds a way to capture the live LVGL screen off the device and rebuild it as a PNG on the host, so UI changes can be verified remotely without a camera. A watcher task polls the USB-serial-JTAG RX for a trigger byte and streams the current screen as raw RGB565 straight to the USB FIFO (framed by ###SHOT_BEGIN/END### with a CRC); firmware/tools/device_shot.py and the device-screenshot skill drive it from the host. Writing straight to the USB FIFO bypasses the primary UART console, which at 115200 baud would take ~37s per frame. The whole capability is behind DESKLOCK_DEVMODE (off by default, enable at deploy time with -DDESKLOCK_DEVMODE=ON) so production spends no internal RAM on the watcher and nothing extra runs on the render path.
