- An update to a grouped notice keeps its arrival time and email state, so the
phone and the email no longer go off again each time it grows.
- Notices carry the names of what changed (newest ten), shown as three and
"and N more": tracks still missing after the scan's move/replacement fold,
duplicate groups new to a sweep, songs merged automatically, and the track
and listener a playback error was for.
- Duplicates found counts only the groups new to that sweep; playback errors
count reports, not the unresolved total.
- A scan failure says what stopped and links to Admin > Library.
- Android: a pile of more than three alerts lists the newest five titles.

- A failed scan run sends scan_failed. Each failure adds to the count and
the notice shows the latest error. A scan cut short by shutdown says
nothing.
- Marking tracks missing sends tracks_missing with a running count.
- A duplicate sweep that proposes a group it had not proposed before
sends duplicates_found, counting everything awaiting review. A sweep
that only re-finds known groups stays quiet, so a read notice isn't
repeated every sweep (CountDuplicateGroupsDetectedSince).
- A playback-error report sends playback_errors, counting the unresolved
errors (CountUnresolvedPlaybackErrors).
The library package gets its notifier as a package-level SetNotifier
beside SetEventBus, for the same reason the bus is package-level.
