Register a task_id. Stdio per-session makes per-port routing unnecessary; this exists for backward compatibility with .claude/commands/*-hermit.md.

Run a coding task using a local LLM (default: qwen3-coder:30b). If background=true, immediately returns {status:'running', task_id} and runs in the background. Check completion with check_task(task_id). Return values: {status:"running", task_id} — running in background (when background=true). {status:"waiting", task_id, question, options} — HermitAgent is asking a question. Reply with reply_task(task_id, message). {status:"done", result} — task completed.

Send a reply to HermitAgent when run_task returned {status:"waiting"}. Return format is the same as run_task (waiting or done).

Check the current status of a background task (use after run_task with background=true). Return values: {status:"running"} — still running. {status:"waiting", question, options} — user input required. {status:"done", result} — completed. {status:"not_found"} — task_id not found (already completed and removed). Use full=true to retrieve the complete result without truncation.

Cancel a running task.
