A third engine beside the alarms' and the timers', and a small one: four
verbs behind a single mutex, no scheduler and nothing that rings. Start,
pause, lap and reset are here rather than on the repository because three of
them arrive as notification buttons and must mean the same thing whichever
surface pressed them.
The verbs guard on the *reading's* mode, not the stored row, so a run whose
anchor a reboot invalidated resumes when the tab says Resume instead of
silently doing nothing; resuming banks the last lap's total first, so the
readout never stands still and never walks backwards. `StopwatchIntents`
namespaces the actions and hands out request codes that cannot collide with
the timers'. The service is reached through one seam, which keeps the engine
free of Android and lets the tests watch the transitions in order.
