Fixes #233

What changed

Domain-warped fBm — low-frequency Perlin offset warps the noise sample coordinates before the main 5-octave fBm pass, breaking grid regularity and producing organic ridgelines
Ridged octave — blends in 1−|noise| to sharpen ridge features and create cliff-like edges
Noise-driven rim undulation — island boundary uses a Perlin offset instead of a hard radial cutoff
5-zone vertex colours — wet dark earth → rocky brown → stone grey → pale limestone → blue-violet crystal peaks
Emissive crystal spire clusters — MeshStandardMaterial with accent emissive, procedurally spawned at high-terrain locations; cluster size, tilt, and spread are all noise-seeded
Noise-displaced rocky underside — radial Perlin displacement + stalactite-style vertical pull on lower cylinder vertices; bottom sealed with a cap disc

- Domain-warped fBm (5 octaves + ridged octave) replaces the previous
  plain 4-octave fBm — warp pass displaces sample coordinates with a
  low-frequency Perlin offset, breaking grid regularity and producing
  more organic ridgelines
- Rim boundary uses a small noise-driven undulation instead of a hard
  radial cutoff
- 5-zone vertex colour gradient: wet dark earth → rocky brown → stone
  grey → pale limestone → blue-violet crystal peaks
- Emissive crystal spire clusters (MeshStandardMaterial with accent
  emissive) procedurally spawned at high-terrain locations using the
  same seeded Perlin noise; cluster size, rotation, and spread are
  all noise-driven for reproducibility without randomness
- Noise-displaced rocky underside replaces the plain cylinder: radial
  Perlin displacement plus stalactite-style vertical pull on lower
  vertices; sealed with a bottom cap disc
