Update on Rust in Zephyr
summary
This update shows a working Rust-on-Zephyr prototype with an RFC for Rust-on-Zephyr, a 5,900-line Rust keyboard app moved from rust-embedded to Zephyr with ~2,600 lines of Zephyr support and ~500 lines of C glue, and about 13,100 lines total tied to the keyboard. It wires cargo+cmake/West integration (cargo invoked during West build), translates Kconfig into Rust cfgs and consts, generates device tree -> module mapping, stubs syscall (K) wrappers, and reports logging and size challenges (one float print added ~35 KB).
