Completes the f64 migration on the CPU data path: the only f32 left now
is the GPU/render/screen layer, which is architecturally required (wgpu
vertex buffers and iced are f32; f64 vertices would double memory).
- EntityTransform::Rotate.angle_rad and Scale.factor are now f64 (the
transform was already applied in f64 around the DVec3 center, so this
only preserves the typed angle/factor). apply_standard_transform and
apply_standard_scale take f64.
- CmdResult::ExtrudeEntity.height and AlignSelected.{angle_rad,scale}
are f64; the EXTRUDE height parses as f64.
- defaults.rs (last-used construction values: circle radius/diameter,
rotate angle, scale factor, offset/fillet/chamfer distance, array
spacing/counts/angle) moved from Cell<f32> to Cell<f64>. Array counts
round-trip through u32 (exact below 2^53).
- Consumers in circle/array/fillet/offset/rotate/scale/align/solid3d and
dimension.rs rotate_point/scale_point follow. `as f32` is kept only
where a value feeds a WireModel rubber-band/ghost (the preview path is
screen-space f32).
