9f6c115001 Implement SX126X SPI and chip configuration for PoC 
- radio.cpp: Add custom SPI bus initialization for boards with non-default pins (conditional on LORA_PIN_SCLK definition). Pass lora_spi object to Module instantiation for SX1262/LR1110.
- radio.cpp: Add TCXO voltage to SX1262/LR1110 chip_begin() as 8th parameter (using SX126X_DIO3_TCXO_VOLTAGE macro or 0 if undefined).
- radio.cpp: Add post-begin SX126X configuration: setDio2AsRfSwitch(), setCurrentLimit(), setRxBoostedGainMode() (conditional on build macros).
- radio.cpp: Fix radio_tx() const conversion for RadioLib transmit() API compatibility.
- config.h: Add LORA_TX_POWER → LORA_POWER_DBM alias for boards like Heltec V3 that define power via LORA_TX_POWER. Use #ifndef guard to avoid redefinition warnings.
- platformio.ini: Add -Wall -Werror to treat warnings as fatal in our code (excluding SDK/framework).
- platformio.ini: Add -std=c99 build flag for KISS C99 support.
- src/kiss.c → src/kiss.cpp: Rename to .cpp so Arduino framework compiles it.

Verified: Builds cleanly for seeed_xiao_s3_wio_sx1262 and heltec_v3 with no warnings.

8883ee3e94 Scaffold PlatformIO project with 20 board configs and C99/C++ source skeleton 
Three-tier configuration hierarchy:
- [env:base] — RadioLib + default LoRa parameters
- [soc_esp32/esp32s3/nrf52] — platform + framework per SoC
- [env:board_name] — board-specific pins + chip selection

20 boards across 4 vendors:
- Heltec: 11 boards (T114, CT62, E213, E290, Mesh Solar, T190, Tracker,
  Tracker V2, V2, V3, V4)
- LilyGo: 4 boards (T-Beam 1W, sx1262, sx1276, supreme)
- Seeed: 1 board (Xiao S3 + Wio SX1262 with verified pins)
- RAK: 4 boards (RAK11310, RAK3112, RAK3401, RAK3x72, RAK4631)

Known/verified pins: Heltec V2/V3/V4, RAK4631, Seeed Xiao S3
FIXME pins: all others (placeholders for future research)

Source skeleton:
- config.h — compile-time defaults + pin validation (#error checks)
- kiss.h/c — KISS protocol implementation (C99)
- radio.h/cpp — RadioLib wrapper with C API (extern "C" boundary)
- main.cpp — Arduino entry point

All files pass pre-commit (prettier, markdownlint, YAML check).
