Full Table (issue from chat): drop the level filter — Full Table tests
regular conjugation patterns, not vocabulary recognition, so restricting
to Basic-level verbs collapsed the eligible pool to two combos
(vivir present, ir future). Pool now draws from all 1,750 verbs. Random
sampling first; if 40 attempts fail we fall through to a deterministic
shuffled scan that guarantees finding any eligible (verb, tense) combo
when one exists. Returning nil now happens only when the user's filters
genuinely produce zero eligible prompts. The view replaces its silent
blank screen with a ContentUnavailableView pointing at the settings
that need adjusting. FeatureReferenceView documents the level exception.
Streak (issue #31 follow-up): activity recording was scoped to flashcard
and Full Table reviews only, so spending an hour on textbook work,
guides, videos, or AI chat could break a "streak" that the dashboard
kept displaying as if it were intact. Three fixes:
1. Extract ReviewStore.recordActivity(context:) — a streak-only entry
point that any user-initiated learning action can call.
2. Add UserProgress.validateStreakIfStale(today:context:) — resets a
broken currentStreak to 0 immediately, called from app launch and
dashboard appear so the displayed number is never a lie.
3. DailyLog formatter pins POSIX locale + current timezone so the
yyyy-MM-dd strings can't drift across locales.
Wired recordActivity into every previously-silent learning action: chat
send, story-quiz completion, textbook exercise submit, grammar exercise
completion, course-deck study finish, week test / checkpoint save,
listening + pronunciation check, cloze quiz completion, lyrics word
lookup, video stream / play / download success, sentence-builder check,
and course-vocab SRS rate (which was bypassing ReviewStore entirely).
