Arena Agent d8d5ea8b6a Repair integration manifests and port nigig exports onto upstream widget families
Restore missing required asset/flow packages from the pinned nigig revision; retain upstream script isolation, X11 hover, and widget-core fixes. Validated makepad-widgets data feature with Rust 1.97.1.

// THE LOOK LIVES HERE. This block is not a reference to the
// engine's shader — it IS the pixel math this effect runs.
// Rewrite it and the effect looks different; everything else
// (geometry, motion, the content coupling, the beat) keeps
// working, because the block SUBCLASSES the engine shader.
// Inputs: t = life 0..1, attr = (id, spawn phase, hue, rnd).
// Signals: self.time_beat (time, beat, phase, pulse),
// self.sig (bar, bpm, energy, dt), self.user (p0..p3),
// self.col_a/b/c/bg, self.fog (density, glow, content, -).
