Podcast cleanup

Goal: a talk recording that sounds clean and even, without changing its content.

1. Call describe_project. Identify voice clips (clips on audio lanes, or media clips whose audio carries the conversation) and any music clips.
2. Tag roles so later steps and the UI know what is what: set_audio_role with voiceover on each voice clip and music on music clips.
3. Denoise every voice clip: set_denoise with denoise: true. Do not denoise music; it smears.
4. Level the conversation: voice clips should sit at volume 1.0; if one speaker's clip is noticeably hot or quiet the user will say so. Adjust only named clips with set_clip_audio (e.g. volume 0.8), never guess.
5. Duck music under speech: on each music clip that overlaps voice, set set_clip_audio volume to ~0.25 and add 0.5 s fades in and out.
6. Trim dead air at the ends: if the first or last clip starts or ends with obvious silence the user mentioned, trim_clip it tight, then add a 0.3 s fade in on the first audible clip and a 0.5 s fade out on the last (set_clip_audio).
7. Report what changed per clip in one short list.
