Add a new guide documenting how to integrate Rust with NuttX, including:
- Prerequisites and supported platforms
- Setup instructions for Rust toolchain
- Required NuttX configurations
- Example build and run instructions for RISCV32 target
The guide provides an experimental but working example of running
a Rust application on NuttX using the rv-virt:nsh board.
