Mutation-testing the worker showed deleting stop()'s cleanup went unnoticed:
Process was incidentally deleting the audio of jobs it should never have
started. The stop test now asserts only the running job was converted (red on
the old code). The timeout test no longer hangs for the 10-minute go test
default when the timeout is removed.

Success path deletes both the upload and the WAV; failures are typed and still
delete the audio; a shutdown mid-job leaves the row for the start-up sweep
(it is not a transcription failure); a hung endpoint is failed by the job
timeout, never an eternal spinner; strictly one job at a time (two long jobs on
iguana were never measured); stopping deletes queued audio and refuses new jobs.
Red: uploads.Worker is undefined.

Bounded read (cap+1 byte tells 'at the limit' from 'over'); a file that fails
validation creates no row; a prober fault is our error, not the user's bad
file; a row whose job cannot be submitted is failed, never left queued.
Mutation-checked: cap off-by-one, missing cleanup and deleting the handed-over
file each turn a test red.

Video is checked first so it is always refused as video; limits and reasons
are typed so callers and tests branch on Reason, not message text.

Probe-based, not extension-based: a Teams voice-only export is typically an
.mp4 with no video stream, indistinguishable from video by name (ADR-033).
Red: package uploads does not exist.
