refactor: signed pattern SDF and extrude cap improvements
- Change pattern eval_sdf to return double (signed distance) instead of pair
- Add reversed parameter to get_local_cap_mat for correct cap orientation
- Add has_end_caps flag to extrude, handle closed axis caps properly
- Add is_closed field to polyline_axis_descriptor
- Use desc.is_closed instead of computing from point/bulge counts
- Fix total_theta calculation in helixline (multiply by two_pi)
- Fix scale vector initialization (zero-fill w component)

fix: Make get_identity_local_to_world virtual to support primitives with multiple subfaces (e.g., cylinder).
Note: Cylinder's side surface defines its AABB, and z-axis scaling does not affect its radius.
Degeneracy checks only consider x/y directions (first two rows of the transform matrix), since z scaling does not change the essential geometry.
TODO: Consider redefining cylinder so the identity transform is always the first subface.
