mathiasandClaude Sonnet 5.5 291a360a83 feat(audio): restrict ffmpeg/ffprobe input to local files and audio demuxers
The upload is attacker-supplied and its CONTENT can steer ffmpeg to open other
files or URLs (HLS/concat playlists). Pins -protocol_whitelist file,pipe and
-format_whitelist to the containers real recordings use, before the input
(after -i it would apply to the output).

Verified with the real static ffmpeg 7.0.2 on koala: real AAC .m4a and WAV
still probe/convert; a crafted concat file is rejected with 'Format not on
whitelist'. Note ffmpeg 7.0.2 ALREADY refused the playlists tried without the
whitelist, so the live check cannot prove the whitelist -- the argv unit tests
do; this protects against a different ffmpeg version being put in the image.

mathiasandClaude Sonnet 5.5 4a0c51d877 test(audio): attacker-supplied input must not steer ffmpeg to other files or URLs (red)
A file's CONTENT can tell ffmpeg to open other paths or URLs (HLS, concat
playlists). ffmpeg 7.0.2 refuses the ones tried, but that is version luck and
the image's ffmpeg is still to be chosen (#34). Pin protocol_whitelist to
file,pipe and format_whitelist to the demuxers real audio uses, before the input.

Red: audio.AllowedDemuxers is undefined.

mathiasandClaude Sonnet 5.5 4352446f36 feat(audio): ffmpeg adapter -- always transcode to 16 kHz mono PCM (ADR-033)
Replaces whisper-server --convert. A zero exit that wrote nothing is an error.
Also fixes the red test's stub, which wrote an empty file and so (correctly)
tripped the no-output check.

Checked against real ffmpeg on iguana with the same argv: AAC .m4a in,
pcm_s16le 16000 Hz mono WAV out, duration preserved.

mathiasandClaude Sonnet 5.5 f84389028d feat(audio): ffprobe adapter implementing uploads.Prober (ADR-033)
Cover art is not video; non-zero exit is the file's fault (ErrUnreadable),
a missing binary / cancelled ctx / bad output is ours. WaitDelay bounds a
cancelled probe whose child holds the pipe open.

Checked against real ffprobe on iguana: JSON shape matches the fixtures and
/etc/hosts exits 1 with 'Invalid data found when processing input'. The unit
tests drive a stub process; ffprobe is not installed on koala.
