Meters: per-channel |L | GR | R| layout (narrower bars). Ceiling lamp now
latches on a limiter catch and holds, clearing after 3s or on click.
Plot: per-channel selectable scrolling in/out/gain-reduction scope under the
meters, fed by new raw block-peak atomics (separate from the decayed bar
atomics). Histories for all four channels run continuously, so switching tabs
keeps each channel's history. Scroll is time-based with a flow-speed selector
(2/5/15/45 s window) so the window length is accurate regardless of frame rate,
with peak-preserving downsampling between columns.
reset() now zeroes the meters so transport restart shows silence rather than
stale values.

Stage 6 begins. Add lock-free Meters (atomics shared audio->GUI) with a
peak-with-decay ballistic, published once per block and gated on the editor
being open. Editor draws a per-channel level + gain-reduction meter panel and
a ceiling lamp fed by the output limiter. Compressor/Limiter expose
gain_reduction_db() for this.
Also add a smoothed per-channel pre-gain applied before each compressor (and
before the All compressor), driving the signal into compression and on into
the limiter for a compressed semi-distortion. Pairs with makeup for full
per-channel input/output gain-staging. Compressor DSP untouched; 16 tests pass.
