• getAudioDuration(path) — ffprobe wrapper, returns seconds | null
• splitAudioFile(in, dir, secs) — ffmpeg -acodec copy chunking
• downloadPodcastAudio(url, dst) — streams HTTP audio to disk
Also moved fetchUrl into util.js (alongside the other stateless
helpers) — it's a generic HTTP-GET-with-redirects used by RSS parsing
and channel discovery, not strictly audio.
server/index.js: 2758 → 2694 lines.
Smoke tested: server boots; /api/license-status, /api/health, /
respond. No behavior change.
