"""ayllu.daemon — always-on-but-cheap listener, learned from the tribe soul-daemon.

The tribe's insight: a persona can be "always on & listening" without burning tokens,
because an idle tick does only a free file/inbox check and a model is invoked ONLY when
a real message arrives. a11oy keeps that insight and adds a hard bound: at most
`max_wakes` model-invoking wakes per run. The daemon itself never calls a model — it
tells the caller WHEN to (via ayllu.loop.run_turn), keeping cost and control explicit.
