Phase 3 core (verifiable): WorkoutAnalyticsAdapter (app data → DaySample),
AnalyticsCoordinator (idempotent backfill of missing weekly/monthly reports +
retention prune, injectable providers), AnalyticsDeepLink (wenza://analytics
report routing).
Fixed a reconcile bug caught by tests: a retention-boundary week was generated
then immediately pruned, regenerating every run — aligned completedWeekStartKeys
to the prune cutoff → idempotent.
Tests: AnalyticsAdapterTests + AnalyticsCoordinatorTests. Verified standalone via
swiftc (~90 analytics assertions total across engine/store/adapter/coordinator).
Remaining (app wiring, notifications, UI) requires an Xcode build — logged in
ISSUES.md as device-only.
