New board: ThinkNode_M9_companion_radio_touch env, variants/thinknode_m9/ (board glue, LR1110 target, keyboard driver, partitions, M9_PORT.md pin reference), boards/thinknode_m9.json, device_caps HAS_THINKNODE_M9 block, HAS_M9_KEYBOARD input path in the touch UI (d-pad focus nav, tab jump keys, QWERTY typing). Based on a contributed bring-up patch by ded (SalishMesh), who also remote- tested every build on a preproduction unit. Hard-won fixes on top of the patch, each verified on hardware: - LR1110 radio init -706: preprod chips run transceiver FW 0x0303, which rejects DriveDiosInSleepMode (0x012A, added in FW 0x0308) that RadioLib 7.x sends unconditionally during begin(). New build-time patch scripts/build/patch_radiolib_lr11x0.py tolerates it on old FW; radio_init() prints the chip's device/FW/errors either way. - TCXO: DIO3 at 3.3 V (the patch's active-oscillator/tcxo=0 theory gave -707 on hardware). - Display: rotation 1 (not 3), plus the missing landscape s_ui_rotation override so LVGL renders 320x240 instead of portrait-into-landscape. - Keyboard: the controller is a separate ESP32-S2 I2C slave (0x6C) with addressed registers - reads select register 0x01 first (bare reads return the HW-version register forever). Boot probe logs the controller's HW/FW; backlight duty register wired. - USB pad release: the keyboard bus lives on GPIO20/21 = the S3's native USB D-/D+ pads, owned from reset by the ROM USB-Serial-JTAG (D+ pullup on SDA). M9Board::begin() releases them before any bus init. - GPIO35-37 are octal-PSRAM pins on the S3R8 - never drive them (the patch's "SD CS = 36" misread package pin 36 = GPIO48; SD is on the shared SPI bus, support returns with PIN_SD_CS=48 later).
