Moves the hardware-change debounce/coalescing worker (the dirty/queued flags and re-queue logic) into a dedicated class with an injectable delay, so the concurrency behavior can be unit-tested deterministically instead of living as an untestable fire-and-forget block in the service. Behavior is unchanged. Adds 3 tests (single rebuild after delay, burst coalesced to one, no rebuild when closed) driven by a controllable delay gate. 199 tests pass (was 196).
