Reactorcoremeltdown b07d758609 Add per-channel VU meters inside the mixer faders (v0.9.0) ...

The render loop now tracks each bus's post-fader/post-FX peak per block and folds
it into a decaying meter value (instant attack, ~300 ms release) plus a clip
latch (~0.8 s when the bus crosses 0 dBFS). Exposed via channelMeter /
channelClipped and surfaced on the ViewModel.

Each mixer fader paints, in one drawBehind, a VU meter inside its volume fill:
rising from the bottom, coloured green -> amber by absolute level with a red tip,
and solid red while the bus clips. A per-frame ticker writes into stable state
objects read only in the fader's draw phase, so meter movement repaints just the
four faders (no recomposition); an unchanged write is a no-op, so a silent mixer
costs nothing but the frame tick.
