Small fix for hot playback cache: eviction keeps current and next only; prefetch up to five tracks when under cap, always fetch the immediate next; grace for the previous current until debounce; run evict immediately on MB or folder changes; re-read cap after download; optional Track.size; live disk usage on Audio settings.
