The reschedule guard is `this._status === 'running' && this.loopTimer === null`,
but the timer callback never nulls `loopTimer`. So the handle stays non-null from
the first fire onward, the guard is false on every subsequent pass, and the Ralph
loop silently stops polling after exactly two ticks.
It stops without changing status: `status` stays `running`, `stop()` is never
called, and no error is raised — the loop just quietly never runs again, which is
what makes it hard to notice on a long autonomous run.
Null the handle inside the callback before re-entering `runLoop()`, which is the
pattern `orchestrator-loop.ts` already uses for its own reschedule.
Test: a regression case in test/ralph-loop.test.ts that runs a real 5ms-interval
loop for ~16 intervals and asserts it ticks at least 3 times. Against the unfixed
source it reports exactly 2.
- Add 24 tests covering Ralph Loop lifecycle
- Test start, stop, pause, resume state transitions
- Test elapsed time tracking and min duration
- Test automatic stopping when conditions met
- Test stats reporting
- Use vi.hoisted() for mock state sharing
