View-only point lights

Add deterministic point lighting to a game visual.

A visual binding can draw a point light around an actor. It changes the view only: the radius, color and flicker never enter simulation state or affect game rules. The radius is in screen pixels, color is a 24-bit RGB number, and flicker is between 0 and 1.

In the Acorn starter, set the tree entry in page.visuals like this:

TS
page: {
  // Keep the other page settings and visuals.
  visuals: {
    ...libraryVisuals,
    "colony.tree": {
      ...libraryVisuals["colony.tree"],
      light: { radius: 68, color: 0xff8a3d, flicker: 0.3 },
    },
  },
}

The light follows each tree that uses this visual. Since it is presentation data, adding or tuning it leaves saved simulation digests unchanged.
