First RP2040 board and third MCU family (after ESP32-S3 and nRF52840). Hardware: RP2040 + SX1262 radio, 850-930 MHz HF, PE4259 antenna switch, LED on GPIO25, no OLED, USB-C via FPC ribbon cable to adapter board. New files: - src/hal/rp2040.rs: MCU primitives (SPI bus, USB driver, flash unique ID MAC) - src/board/waveshare_rp2040_lora.rs: board implementation - ld/rp2040-memory.x: linker memory layout Also fixes cortex-m-rt/set-vtor (moved from global dep to per-board feature, since Cortex-M0+ has no VTOR register) and makes build.rs memory.x selection target-aware.

//! DongLoRa firmware — transparent LoRa radio over USB.

//!
|
|
//! Three async tasks communicate via static channels:
|
|
//!
|
|
//! ```text
|
|
//! host_task ──Command──► radio_task ──► SX1262
|
|
//! ◄──Response── │
|
|
//! StatusWatch
|
|
//! ▼
|
|
//! display_task (optional)
|
|
//! ```
|
|
//!
|
|
//! The host drives everything. The radio idles until commanded.
