Poem

🐰 I found a note in skillful trails,
Where audio hops with Opus tales.
.opus and .ogg now softly sing,
A tiny doc change with a tidy spring.

- Line 60: Update the `--audio` flag documentation to state that it accepts
Opus-format files and explicitly list supported extensions by name (e.g.,
".opus" and ".ogg") to match runtime behavior; reference the `--audio` flag text
in SKILL.md and replace the sentence "only Opus-format files" with a clarified
line like "Opus-format files (e.g., .opus and .ogg) are supported" so users know
.ogg is mapped to Opus at runtime.
