hermes - 💡(How to fix) Fix [Bug]: Kanban workers are not cancelled when reclaimed due to timeout/stale_lock

As I had to restart the gateway to get it back under control, I lost the server logs that covered the time the dispatcher was misbehaving. 

I would prefer not to post `hermes debug share` as there's a LOT of message history and local paths in there. I could not see any messages related to the lock or worker reclamation.

Here's one of the workers' chat logs. Note how there's 1 worker trying and failing to mark its task as complete, another just getting started with its task, and then out of nowhere a third worker spins up.

    The task appears to be in a terminal state despite kanban_show reporting running. This may be a race condition. Let me check if the child task received relevant context:

Let me now look at the tiny fallback implementation and the modality harnesses to
 understand the fallback mechanism more deeply.

┌─ Reasoning ──────────────────────────────────────────────────────────────────┐
I see - the child task t_9d4e96e5 is waiting for all three parent tasks to complete
, including t_6fe2bd6e. The parent tasks are: t_6fe2bd6e (datasets), t_58226975 (
model quality), and t_d1e39a01 (infrastructure). 

The completion error "unknown id or already terminal" is strange because kanban_show
 still shows it as running. This could be a timing issue where the task was completed
 between my show and complete calls. Let me try one more time with a fresh show call
 first.

Actually wait - looking at the event log again, run 4 is the current run. The task
 is still running. The completion error might be due to some other issue. Let me try
 again.

Now let me check the DNA harness and protein harness to see how they handle fallback
s too.

┌─ Reasoning ──────────────────────────────────────────────────────────────────┐
The task completion is failing repeatedly. Let me try a different approach - maybe
 I should check if the task has actually been completed by another run or process
. Let me try one more time with a fresh kanban_show to get the latest state.
