Widget-refresh plumbing that Calendula's 2.24.0 widget refactor needs, and that Agendula already hand-rolls.
- `GlanceAppWidget.updatePlaced(context, receiverClass)` redraws every placed instance using ids from `AppWidgetManager` + `getGlanceIdBy`. `updateAll` uses Glance's provider-name map, which is empty in a process that hasn't hosted a widget session yet, so the redraw gets dropped (calendula#18, calendula#420).
- `updatePlaced(..., bumpRefreshStamp = true)` also moves each instance's `currentRefreshStamp()`. An update to a running session only recomposes and never re-runs `provideGlance`, so a widget that keys its data load on the stamp reloads there too. This is the per-widget `data_stamp` idea from calendula#420.
- `WidgetRefresher` turns a burst of "data changed" requests into one debounced redraw, the generic part of Agendula's `TaskWidgetUpdater`. Calendula will use it for its own writes, so they don't have to wait for `PROVIDER_CHANGED`.
- `FloretWidgetUpdateReceiver.extraRearmInterval` lets extra actions also re-arm the rollover alarm, at most once per interval. This moves Calendula's 15-minute `PROVIDER_CHANGED` backstop upstream. It defaults to off, so Agendula is unchanged.
