Audio files were previously skipped as unreadable binaries. This adds: - `is_audio()` detection via magic bytes (ID3, RIFF/WAVE, fLaC, OggS, ADTS, M4A ftyp box) with extension fallback - Audio metadata extraction via `ffprobe`: title, artist, album, genre, year, duration, bitrate, codec, sample rate - `build_user_content()` audio mode passes rich metadata as text context so the LLM can suggest a name based on embedded tags - 13 new bats tests covering detection, metadata, and end-to-end naming - README updated with audio formats and ffprobe optional dependency Closes marksverdhei#19
Closes marksverdhei#6 Before the hat animation runs, --preview prints a content snippet to stderr so you know what the file contains without opening it: - Text files: first 8 lines + total line count - Audio files: title, artist, album, duration from ffprobe tags - Images: dimensions, colour mode, key EXIF fields (Make, Model, DateTime) The preview goes to stderr only, so stdout output (the suggested name) is unaffected for scripting. Adds 6 new bats tests (44 total). Example output: ── preview: interview-recording.mp3 ── Title: Q3 Planning Call Artist: Zoom Recording Duration: 42:17

Summary
Closes #6
Adds
--preview/-pflag that prints a content snippet to stderr before the hat animation, so you can see what the file contains at a glance:Text files — first 8 lines + total line count:
Audio files — ID3/FLAC/OGG tags via ffprobe:
Images — dimensions, colour mode, key EXIF fields:
Preview output is stderr-only — stdout (the suggested name) is unchanged for scripting. Works alongside
--quiet,--batch, and--dry-run.Test plan
