rayhpeng c72bccb916 fix(schedule): guard task saves with an optimistic version CAS ...

update/pause/resume read the aggregate and persist it whole; a dispatch
or completion committing between those operations previously got
overwritten by the stale snapshot -- rolling back next_run_at,
run_count, and last_run_id, after which the next poll re-launches an
already-executed occurrence.

- ScheduledTask gains a `version` token owned by the storage write path;
  every committed write (save CAS, record_launch, record_completion,
  claim_due, cancel_stuck_once_tasks) increments it.
- `save()` is now a compare-and-set on that version: a stale write
  raises the new ConcurrentUpdateError instead of committing.
- The service retries the read-modify-write (re-applying the aggregate
  transitions to a fresh read) up to 3 times, then surfaces the
  conflict for the router to map to a retryable 409.

Also exports LaunchIndeterminateError from the package root, missed in
the previous commit.
