- Fix queue flush race: clear is_queued under mutex only; never move
pilot_w backwards (would break r<=w ring-buffer invariant). Worker
skips stale entries via new is_queued guard at start of pilot_realload
- Add early-exit in pilot_realload when is_queued==0 (entry flushed
between enqueue and worker pickup), preventing unnecessary loads
- Fix misleading EMA struct comment: momentum_logits is used only by
the PILOT prefetcher, not blended into actual MoE routing decisions
- Fix Slot pinned comment: 'never evicted' was too strong; clarify that
pinned slots may be displaced under extreme all-pinned cache pressure
- Use st_read_f32() for scale tensor (.qs) instead of st_read_raw() to
handle potential future BF16/F16 dtype changes robustly
