The completion side-effect (add to history unless private + markDownloaded on
the source MediaItem) was duplicated in applyEvent('done') and the preview
fake-ticker, and had already drifted (the preview copy omitted formatId/
formatHasAudio). Extracted one recordCompletion(item) helper that both call.
Also tightened a latent bug: the old applyEvent ran markDownloaded for any
'done' event with a mediaItemId, even when the item was canceled (the reducer
keeps canceled items as 'canceled'). recordCompletion now runs only when
status === 'completed', so a canceled collection item is no longer wrongly
marked downloaded (and will be retried on the next re-sync).
typecheck + 242 tests + eslint green.
