Covers the pure pw-cli parser seam: multi-node parse sorted by description
(non-audio dropped), Source=>input / Sink=>output, description-falls-back-
to-name, empty/non-audio inputs yield nothing, EOF-flush of the final block,
and incomplete blocks (no media.class) dropped. pw_cli tests 0 -> 6.
Implemented by Gemini per next-task.md; left uncommitted per the operating-
agreement default, reviewed against the real diff and re-verified (build +
clippy --all-targets + test all green) by the senior.

Splits the pw-cli output parsing out of enumerate_audio_devices into a pure
fn parse_pw_nodes(&str) -> Vec<AudioDevice> (with a push_device helper),
leaving only the subprocess call in enumerate_audio_devices. Behavior-
preserving — same id-block boundaries, Audio/* filter, Source=>input,
description-falls-back-to-name, and sort-by-description. Creates a testable
seam (the parsing had zero coverage). Build + clippy clean.
