Watched-status: persistent red bar + our play count (vc=74 items 2,3)

Item 2: thumbnail progress bar now stays full on watched videos — falls back to watch-history when the live resume point is gone (was vanishing on finished videos). A live resume entry still wins for mid-watch progress. Item 3: HistoryStore tracks a per-video playCount (increments each watch, carried forward atomically in recordWatch; defaults 1 for pre-vc74 entries). VideoDetail shows 'Watched N times' under the view count.
