"""DELETE /swarm/hosts/{uuid} — decommission a worker.
Removes the DeckyShard rows bound to the host (portable cascade — MySQL
and SQLite both honor it via the repo layer), deletes the SwarmHost row,
and best-effort-cleans the per-worker bundle directory on the master.
Also asks the worker agent to wipe its own install (keeping logs). A
dead/unreachable worker does not block master-side cleanup.
