Add editor/gain_curve.rs: a square panel beside the scrolling plot showing the
channel transfer (out vs in, -60..0 dB) for whichever channel the plot tab
selects. Plots the full wet path — out = (in + pre_gain) + gain_reduction + makeup
— using the shared Compressor::gain_computer (now pub) so it matches the DSP and
the GR meter. Unity-reference diagonal + threshold marker; mix not folded in.
Update README structure/status to reflect the editor/ widget module and the
completed Stage 6 visualisers.

Flag each plot bucket with whether the output limiter hit the ceiling
(limiter GR > 0.1 dB), carried through ScopeRing as a per-bucket hit field and
folded into history columns. The editor draws a short red tick at the top of any
hit column (one column wide, so runs merge into segments and a lone hit is a
dot); nothing otherwise. Global marker, shown on every channel tab.

Feed the scrolling plot from a lock-free SPSC ScopeRing instead of sampling one
atomic per egui frame, so horizontal resolution is set by the audio-clocked
bucket rate (~200 Hz) rather than the ~60 fps repaint. process() accumulates a
bucket every sample_rate/BUCKET_HZ samples (peak-preserving, spanning blocks)
and pushes it; the editor drains all new buckets each frame and folds them into
PLOT_N columns. Fast transients between frames are no longer dropped, and the
plot is now audio-clocked (freezes on pause, falls to silence on stop/reset).
Drop the per-frame plot_* atomics (the per-channel lamp now reads the decayed
bar level). Also fix the area fill: render it as a strip of per-segment convex
quads instead of one concave polygon, which egui fan-filled from a corner and
left stray triangles.

Draw a translucent area from each level line down to the plot baseline so the
input and output traces read more clearly. The gain-reduction trace stays a
plain line (it hangs from the 0 dB line, where a fill would read oddly).

Move the egui editor from a single editor.rs into an editor/ module: mod.rs
(aggregator: create(), EditorState, layout, placeholder slider columns),
meter.rs (|L|GR|R| meters + ceiling lamp, owns MeterState), and plot.rs
(rolling in/out/GR plot, owns PlotState + PlotHistory). Each visualiser owns
its GUI state; the aggregator composes them. No behavior change.
