Pure advanceStreak (1-day grace none, milestone flags at 3/7/14/30), persisted in the save blob; StreakNotifier advances on every finished attempt; home screen flame chip and milestone snackbar. Fix flutter create's camelCased iOS bundle id and underscored Android application id to the agreed lowercase form before any store registration. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
