- The mission tick now runs two idempotent sweeps: auto-start flips Scheduled
missions whose start time has arrived to Active, and auto-complete sets
missions whose scheduled window (start plus duration) has fully passed to
Completed with a stamped completedAt.
- Side ops are created as quiet Ready drafts and committed with a "Mark as
Scheduled" control, which is what posts the Discord roll-call and hands the
op to the lifecycle above.
- Daily schedule reminders nudge the creator to set a draft live (web
notification plus Discord DM).
- Adds the mission lifecycle/commit event types and the matching notification
labels, and updates the bot docs.
