Function updateVertexPosition

updateVertexPosition(
    geometry: BufferGeometry,
    vertexIndex: number,
    position: [number, number, number],
    vertices?: VertexData[],
): void
Update a vertex to an absolute position.

Handles deduplicated vertices by updating all original buffer indices.
Parameters
- geometry: BufferGeometry
  The BufferGeometry to modify
- vertexIndex: number
  Index of the unique vertex
- position: [number, number, number]
  New absolute position [x, y, z]
- Optionalvertices: VertexData[]
  Optional vertex data for deduplication mapping
Returns void
