Detailed Description

Scoped guard for a FreeRTOS recursive mutex.

Takes the recursive semaphore on construction and gives it back on destruction. Tolerates a nullptr handle (no-op), so it can guard an optional/opt-in lock. The same task may nest acquisitions, which a plain MutexGuard would self-deadlock on.

Not safe to call from ISR context.
