complete_task authorised a terminal transition by task status alone; the
`current_run_id = ?` fence only applied when the caller volunteered
expected_run_id (derived from HERMES_KANBAN_* env). A human at the CLI, an
orchestrator session or any env-less caller therefore marked a `running`
card done and _end_run closed the dispatcher worker's run row while that
worker kept executing (#111764).
Mirror the fence request_review already carries: a `running` task under a
live claim needs expected_run_id (worker ownership) or force=True (explicit
operator override), otherwise LiveClaimError. `hermes kanban complete
--force` and the dashboard's "mark done" (a human action) carry the override;
the kanban_complete tool reports a structured refusal. Completing `ready`,
`blocked` or `review` cards without a claim is unchanged, so the manual /
orchestrator flows PR #73188 pinned keep working.
