//! Schedule data service — surfaces every cron job (enabled or paused)
//! as a uniform `Vec<McScheduleItem>` for the schedule panel.
//!
//! Pending-approval rows aren't yet wired here; they'll join when the
//! approval queue grows a global accessor (today it's session-scoped
//! state inside the agent loop). The `McScheduleKind::PendingApproval`
//! variant on the type side is ready for that data the moment it lands.
//!
//! `list` is async because the cron registry lives in the SQLite DB —
//! the renderer pre-fetches once on `actions::open` rather than calling
//! during each `draw`, so the per-frame cost is just a `Vec::clone`.
