EPIC: Schedules, events and attention

Programme: #1

Own durable schedules, source events, condition watches, missed-run policy, notifications, approval queues and bounded unattended work.

## Child issues
- [ ] #92 AUTO-01 — Durable schedules and source events
- [ ] #93 AUTO-02 — Notifications and bounded unattended work

## Cross-cutting gates
Duplicate events cannot duplicate consequential actions, sleeping devices do not blindly replay expired intent on wake, execution location is explicit, quiet hours are respected, and unattended work cannot widen its own grant.

Start by reading child issues #92 and #93, then compare their scope with the cross-cutting gates in this epic. Map schedules, source events, notifications, approvals, and unattended work to the stated constraints. Done means the child work covers duplicate-event protection, expired intent on wake, explicit execution location, quiet hours, and bounded grants.
