Function twistExtrude

twistExtrude(
    wire: Wire,
    angleDegrees: number,
    center: Vec3,
    normal: Vec3,
    profileShape?: ExtrusionProfile,
    shellMode?: boolean,
): Result<Shape3D | [Shape3D, Wire, Wire]>
Extrude a wire along a normal with helical twist and optional profile scaling.

Constructs a helical auxiliary spine that rotates the profile by angleDegrees over the extrusion length. Combines twist with optional s-curve or linear scaling when profileShape is provided.
Parameters
- wire: Wire
  The profile wire to sweep.
- angleDegrees: number
  Total twist rotation in degrees. Must be non-zero.
- center: Vec3
  Start point of the extrusion spine.
- normal: Vec3
  Direction and length of the extrusion. Must be non-zero.
- OptionalprofileShape: ExtrusionProfile
  Optional scaling profile applied along the extrusion.
- shellMode: boolean = false
  When true, return [shell, startWire, endWire] instead of a solid.
Returns Result<Shape3D | [Shape3D, Wire, Wire]>
Result containing the twisted extruded shape or a shell tuple.
