feat(boards): RAK4631 WisBlock bring-up + build-system cleanup
RAK4631 board: - SX126X_POWER_EN on P1.05 driven HIGH at init (radio is power-gated; without this the chip has no power and SPI hangs) - HFXO + LFXO external crystals in embassy_nrf::Config (USB CDC-ACM needs +/- 500 ppm which the internal RC oscillator can't provide) - SoftwareVbusDetect(true, true) so USB enumerates without needing a CLOCK_POWER interrupt handler - Green LED on P1.03 via SimpleLed (RAK19007 Base LED1, active HIGH) - driver/mod.rs: open simple_led feature gate for rak_wisblock_4631 - Spim::new pin-order comment on SPI setup (arg order is sck/miso/mosi, not sck/mosi/miso — easy to get wrong) debug-checkpoint instrumentation (feature-gated, zero cost in release): - radio.rs: debug_blink::set(N) at each TX-phase boundary, filling in the long-aspirational blink-map doc - debug_blink.rs: checkpoint 19 between prepare_for_cad and cad(), so future bring-ups can distinguish modem-setup hang from DIO1-wait hang justfile + mise.toml: - set shell := ["mise", "exec", "--", "sh", "-c"] so recipes always resolve tools through mise, not whatever happens to be on PATH - replace per-board := vars + long if/elif _info chain with a single case statement — one place per board, two lists (names + metadata) - new flash-dfu recipe using adafruit-nrfutil via uvx, with VID:PID (239a:0029) port autodetect for the Adafruit nRF52 bootloader - mise.toml: rust pins now carry ARM targets + clippy, so 'mise install' is sufficient bootstrapping (no extra rustup target add steps) Verified TX on real hardware (RAK19007 Base + RAK4631 Core + RAK1921 OLED, US915 band): ADVERT round-trip with an external receiver.
