Mastering is faster now: up to 4 tracks at once

We scaled the engine: the service now processes up to 4 tracks in parallel instead of strictly one at a time. In a test on our production server, four tracks that took ~43 seconds back-to-back are now ready together in ~14 seconds — 3x faster under load. At peak times your track no longer waits in a shared queue.

Plus reliability: every master now reliably finishes — no more jobs stuck in a processing state. We verified quality under load with a stress test: the sound is identical to one-at-a-time.
