- Fix `enhanced-determinism` not producing cross-platform deterministic results for parry3d/parry3d-f64.
The feature now enables `glamx/scalar-math` to disable architecture-specific SIMD (NEON on arm64,
SSE2 on x86_64) which caused floating-point non-associativity in Vec3/Vec4/Quat dot products.

- Oriented (one-sided) 2D polylines ([#254](https://github.com/dimforge/parry/issues/254)). Build a `Polyline` with
`PolylineFlags::ORIENTED` via `Polyline::with_flags`, or toggle it with `Polyline::set_flags`, to clamp contact normals
to the outward side. This removes the spurious sideways push a body gets at a convex corner of a thin double-sided
polyline. A single 2D flag covers what `TriMesh` splits across `TriMeshFlags::ORIENTED` (assume an outward orientation
and compute pseudo-normals) and `TriMeshFlags::FIX_INTERNAL_EDGES` (use them to clamp contact normals). Also adds
`Polyline::flags`, `Polyline::segment_normal_constraints`, and the `PolylineFlags` / `SegmentPseudoNormals` types.
