Clipped blocks were broken at UTM and lost their clip when pasted into
another drawing.
- Clip geometry: world_clip_polygon_f64 keeps the boundary in absolute f64;
clip_wires now clips in a frame relative to the boundary's first vertex
(small coords → exact f32 Sutherland–Hodgman) and re-splits the result
into the double-single high/low pair the relative-to-eye renderer needs,
so the clipped block draws correctly and no longer poisons ZOOM Extents.
- ZOOM Extents (fit_all): the outlier reject compared absolute UTM
coordinates against a centre-RELATIVE span (local_extent_max), rejecting
the whole drawing → no-op. Made the reject distance-from-median-centre.
- Cross-drawing paste: clipboard now snapshots each copied entity's whole
xdictionary object graph (ClipboardDeps.ext_objects) and recreates it on
paste with fresh handles + remapped references, re-pointing the pasted
entity's xdictionary at the new root. Wired into PASTECLIP and PASTEORIG.
Fixed handle allocation (allocate_handle, not the non-advancing
next_handle) so the dictionary chain doesn't collapse onto one handle.
- Updated hit_test / plugin_host tests for the eye-relative + DVec3 signatures.
Known gaps: PASTEBLOCK does not yet carry the clip (clip would need to live
inside the new wrapper block definition); hatch-clip path still f32.

Route the remaining absolute-coordinate CPU projection through the
relative-to-eye path so it no longer multiplies by a view_proj matrix
carrying a ~1e7 translation (which cancels catastrophically in f32 after
world_offset removal):
- camera pick_on_plane / pick_on_target_plane delegate to
unproject_on_plane_f64 (rotation-only inverse + f64 eye)
- snapper (world_to_screen), hit_test (click_hit / mesh / hatch), the
scene mesh/solid hit methods, grid + UCS axes, and polar_constrain_near
all take view_rot + eye and project relative-to-eye
- compute_grid_step measures the per-unit scale via the rotation-only
matrix (no eye term needed)
view_proj remains only for conservative CPU frustum-cull / scissor and the
screen-space viewcube / UCS-icon directions. NOTE: SnapResult.world and
the command-point chain are still Vec3 (f32) — a ~0.5 m quantization at
extreme UTM zoom remains; the command layer goes f64 next.

Box, window, crossing and lasso selection only tested wires and hatches, so
3D solids (which render as meshes) could never be selected that way. Add
mesh_box_hit / mesh_poly_hit that project the solid mesh and test it against
the box / lasso (window = all vertices inside, crossing = any vertex inside
or the region sitting inside the solid), and wire them into the selection
paths.
Also re-tessellate solids after a move/rotate/scale/mirror/copy: the entity
moved but its cached mesh didn't, so the solid stayed drawn at its old
position. Rebuild the mesh caches when a transformed/copied handle is an
ACIS volume.

Move the 30 flat modules under src/scene/ into six folders by role:
convert (entity→geometry), text (fonts/shaping), model (render models),
pick (hit-test/selection/grips/xclip), view (camera/transform/render),
cache (block + property caches). pipeline/ is unchanged.
Full path migration — all `scene::X` references become
`scene::<group>::X`, no compatibility re-exports. render.rs items that
were `pub(super)` (parent was scene) become `pub(in crate::scene)` to
keep their original scene-wide visibility.
No behavior change; build and tests are green.
