Adds full array/waveform support through the synthetic DSP engine: a
dsp.Sample value model (scalar or []float64), array ops (index, slice,
sum, mean, min, max, length, fft) with an in-tree radix-2 FFT, and static
type propagation (OpOutputType) that the editor mirrors to colour wires by
data type and flag invalid wirings. Stateful filters and lua stay
scalar-only. Adds a waveform plot mode (x-vs-index trace).
Also: errored-node hover reasons, S/N add-signal/add-node HUD shortcuts in
the synthetic editor, and view-mode widgets that blend with the canvas
background (chrome kept in edit mode).

Extend the panel logic editor with two capabilities:
- action.widget: drive a panel widget by id from a flow — enable/disable,
show/hide, and (for plot widgets) clear, pause, or resume the live plot.
Wired via a per-widget command store consumed by a Canvas WidgetView wrapper
(disable overlay / hide) and PlotWidget (pause/clear), reset on panel unmount.
- action.export now emits multiple named arrays as CSV columns with per-column
labels and an alignment mode (common/any/interpolate); dialogs support asking
for and displaying multiple values per dialog.
