Detection already cleared the session after 3x 401/403 but did so silently —
the widget would just go stale. Now fires a one-time HIGH-priority notification
on its own 'Sign-in alerts' channel that opens LoginActivity for re-paste.
Replace the configurable threshold sliders with two fixed alert levels —
90% and 100% — per metric. Anti-spam now uses hysteresis instead of the
API reset-epoch (which could drift and re-fire): each level fires once
when crossed and re-arms only after usage drops back below it. Alerts are
posted only by the background worker, never the in-app refresh loop, so
you're not pinged while looking at the app. UI drops the sliders for a
one-line description; settings keep just the on/off switch.

Add an in-app 7-day history chart and opt-in usage alerts, the two
features requested from the macOS Claude-Usage-Tracker that map cleanly
to an Android widget app.
History:
- UsageSnapshot model; PreferencesManager records session/weekly
utilization on every refresh (7-day retention, <=600 points, collapses
readings under 2 min apart to avoid worker+manual double-logging).
- HistoryChartView: dependency-free Canvas line chart (session/weekly,
0/50/100% gridlines), breaks the line across >35-min gaps.
- New HISTORY card with chart + legend.
Notifications:
- Notifier posts when session/weekly crosses a user threshold, at most
once per limit window (keyed on reset-epoch, re-arms on rollover).
- USAGE ALERTS card: enable switch + session/weekly sliders (50-100%,
defaults 90/85). POST_NOTIFICATIONS permission + runtime request.
- Wired into the existing 5-min background worker.
