Author a music track and volume (0-100%) per story node; the runtime
scales it to 0-1 and applies it without restarting the track when only
the level changes. Adds migration 024, threads music_volume through the
repository/runtime, and gives the node inspector a volume slider.

A dry synthesized key-clack (filtered noise burst with pitch jitter) plays as
each line types out — every other non-space character — for a detective-terminal
feel. Skipped in the editor preview and when reduced-motion is set.

sfx() bailed whenever the context wasn't already 'running', so the autoplay-unlock
race dropped the blips. It's invoked from a click, so resume the context there and
always schedule the tone; bump the envelope and use a triangle wave (with a small
up-chirp on choices) for a more audible cue.

- migration 023: story_nodes.music_asset_id (references the asset store).
- src/audio.ts: a tiny audio manager — one looping scene-music track (fade,
dedup, gesture-primed autoplay) and synthesized one-shot SFX; global mute.
- Runtime: RuntimeNode.musicUrl; music follows the current node (null inherits,
a finished playthrough stops). SFX blips on dialogue advance/choice (not in the
editor preview). Floating mute toggle during play.
- Graph inspector: a "Scene music" picker sourced from uploaded audio assets.
No external library (we did not adopt react-winamp — it is a React 16 CRA app,
not an installable package). Bundle grew ~2 KB.
