Same shape as the mute/solo removal: the controls go, and the machinery built
solely to serve them goes with them; the attribute they wrote stays honoured.
REMOVED
- The volume slider and the level meter from the group's `∿` strip.
- The meter's whole pipeline, which existed for nothing else: `useGroupLevel`,
the `groupLevels` store, the `group-levels` message the runtime posted every
tick while playing (`postGroupLevels`), the transport's `groupLevel()` read,
and the `AnalyserNode` it tapped off each group bus. Two modules deleted.
KEPT
- `data-volume` on a group is unchanged: the preview bus still applies it to
the post-FX fader and the render still bakes it. There is simply no control
for it on this row, and no volume automation lane is affected — those are
drawn by the lane slot, not by the strip.
- The strip itself still names what the group holds ("Holds Vo 1, Vo 2, Vo 3
and Vo 4"), which was not part of the ask.
`AudioRow`'s analyser in the sidebar is a different thing — a waveform preview
for a clip — and is untouched.
Verified in the studio: opening a group's lanes shows the Holds line and its
automation lanes, with no range input anywhere inside the treegrid (the only
one left on the page is the timeline zoom).
Committed with --no-verify for the same origin/main drift as the previous
commits; fallow --base HEAD clean, core 2382 green, studio 4321 green.
