feat(editor): procedural noise generator, sky presets, viewport lighting

Browse source 
- Noise Generator in Sculpt panel: applies procedural value noise
  with configurable frequency, amplitude, octaves, and seed
  to create hills/valleys across entire tile instantly
- Sky/Lighting presets: View > Sky menu with Day (blue sky, high sun),
  Dusk (orange, low sun), Night (dark blue, moonlight)
- Viewport clear color and light direction now configurable at runtime
- Noise uses smoothstep interpolation with octave fractal layering
