JMR-devandClaude Opus 5 5042d73770 feat(media): add ffmpeg decode, probe and FLAC extraction helpers

Lifts decode() out of scripts/smoke.py, where it was duplicated verbatim in
scripts/bench.py, and adds the probe and extraction calls the pipeline needs.

Command construction is separate from execution so argument lists can be
asserted directly instead of by monkeypatching internals. flac_command always
passes -sample_fmt s16: the FLAC encoder accepts only s16/s32 while AAC and
Opus decode to fltp, so leaving it to filter-graph negotiation can fail.

The default profile keeps the source rate and channels, since lossless
extraction is the point of choosing FLAC; downmixing to 16 kHz mono happens
at decode time instead.
