 A task mob is a non-violent "worksite" — build a solar panel, survey flora, prospect a rock — that reuses the entire combat engine. Set `kind: task`. Mechanically its `hp` is a hidden work pool that drains to 0 to **complete** the work; the player sees a progress bar filling toward 100%. A task mob **never attacks back** — the danger (if any) comes from a room `hazard:` (see `hazards.md`). Use the `work` command (or `attack`) on it.
