ruv 347ad4bb11 feat(pointcloud): Hollywood face fx — webcam texture, wireframe, scan line ...

Adds optional cinematic effects to the face-mesh demo, all toggleable
via a new ?fx= URL param. Default is 'all' (texture + mesh + scan +
halo). Lightweight modes available: ?fx=clean (texture only) or
?fx=points (original solid amber).

- Texture: per-frame webcam → hidden 2D canvas → getImageData lookup
  at each landmark (and each interpolated edge sample). Splats now
  carry the visitor's actual skin tone, not solid amber. Sampling is
  mirrored on x to match the selfie convention used by the face mesh
  vertex placement. All on-device — no frames leave the browser.
- Mesh: persistent THREE.LineSegments overlay drawn from
  FACEMESH_TESSELATION (~1300 edges). Translucent (opacity 0.35),
  amber, additive blending, depthWrite off — gives a holographic
  wireframe wrapping the point cloud. Geometry is updated in place
  each frame; only positions get re-uploaded.
- Scan: vertical bright slab sweeps top→bottom every 4 seconds,
  amplifying splat color up to 2.6× when within ±0.08 world units of
  the line. Westworld-style scanning.
- Halo: existing 60-particle ring around the face is now opt-in via
  FX_HALO. Cleaner default for the texture-mesh combination.

Info panel surfaces active fx list in face-mesh mode. Synthetic
fallback hides the wireframe overlay so it doesn't render against an
empty figure. Workflow README updated with the new ?fx= options.
