/we:resume

Continues the work this session was doing when a stop cut it off. The built-in /resume reopens an
earlier conversation; /we:resume runs inside the conversation and restarts its work. One word from
the user is the whole instruction: ask nothing the open-items list already decides.

1. Open items. Read the open-items list ("Offen", "what's left", "next") of the last report in
   this session. After a compaction, read the transcript tail for it. No list → name the last task
   in one line and continue it.
2. Workers. ListAgents, then per worker:
   • stopped mid-task → SendMessage(to=<name>, "continue where you stopped");
   • already reported → shut it down and verify it is gone (TaskStop, or no process under
     /proc); never restart it.
3. Waits. Re-arm the monitors and background waits the stop killed: the CI watch on each open PR
   (${CLAUDE_PLUGIN_ROOT}/scripts/watch-pr-checks.sh <PR> as a background command), rollout and
   deploy waits.
4. Go. Say in one line what resumes, then work the open items in their order. A merge outside a
   run's standing auto-merge (orchestrate § Close the run) or a release still needs the user's word.
