MechaCat02 25704c5811 Re-baseline sylpheed_n50m golden post-AUDIT-032 ...

Companion to 49f3eaf (AUDIT-032 dedicated audio worker). With the
audio callback ticker now on by default, the boot trajectory at
50M instr changes:

  instructions  50000009 -> 50000002  (interpreter stop boundary shift)
  imports         407215 -> 40454     (-90% — left audio-wait busy loop)
  swaps                2 -> 1         (degenerate splash repeat lost;
                                       main thread advances past splash)
  draws                0 -> 0         (audio gate != renderer gate per
                                       AUDIT-032 methodology correction)

The 10x imports drop reflects exiting the NtWaitForSingleObjectEx
busy-wait pattern (1.49M -> 30 calls per audit-runs/audit-048-*).
Boot now reaches Stfs/Xam content/crypto init phase. The single
remaining swap is the first splash; main thread is then blocked on
a different handle (0x1280) for follow-up.

sylpheed_n2m unchanged — at 2M instr the audio worker hasn't fired
yet, so the digest is byte-identical pre/post AUDIT-032.

Verified deterministic via two consecutive --expect runs at the new
digest (cargo test -p xenia-app --test sylpheed_oracles -- --ignored
passes in 2.82s).
