Opt a character into its per-character background features (offscreen-life heartbeat/
scene, story-room, ambient-life). Proactive does NOT need this — it is on by default and
globally swept (runtime-controls audit §12 item 6, policy A). These features are opt-in,
and EACH is a recurring **paid** LLM Temporal workflow under a standardized
``{feature}-{slug}`` schedule. Idempotent: re-activating an already-active feature is a
no-op (reported under ``already_active``). App-scoped — 404 if the slug is not owned by the
caller's app. This replaces the ad-hoc manual ``scripts/character_*_schedule.py`` runs.
