Curved 3D-solid faces backed by an ACIS cone-surface (e.g. the arched
mullion bars of a storefront curtain wall) were swept a full revolution
regardless of the face's actual angular extent, so a bar bounded to an
8-16 degree arc rendered as a full circle of the surface radius — a large
jagged loop instead of a small arch.
cone_faces (the truck B-rep path) now derives the angular span from the
face's boundary loop and rsweeps only that arc; the bespoke fallback
tess_cone_face no longer forces a full revolution when a thin face
collapses to a single height. Arc extraction uses a seam-robust
largest-gap method so faces straddling +/-pi (the crown of an arch) are
not mistaken for full circles.
Verified against Clinic_Architectural.dwg: the seven arch-bar solids drop
from a ~12.9 (2R) bbox to their true ~1-2 unit extent, and a file-wide
check of 155 cone-bearing solids shows none ballooned and none collapsed.

Opening / navigating a heavy 3D DWG (e.g. a BIM model with ~10k ACIS solids)
was effectively frozen. Several independent costs, all addressed here:
- Face3D edge/fill buffers were re-uploaded on every camera move (keyed on
camera_generation). They are world-space and selection-independent, so gate
them on (geometry_epoch, fill_mode) instead — a pan no longer re-walks every
wire.
- Solid meshes were drawn one buffer + one draw call per solid (~10k draws/
frame), which strangled the GPU front end. Concatenate every solid's LOD0
into a few large buffers (split only to stay under the 256 MB buffer cap) and
draw the whole set in a handful of calls. Built once per geometry epoch, so
selection / hover never re-pack it.
- Selection / hover highlight is now a small tinted overlay of just the picked
solids, drawn last with an Always-depth pipeline so it shows on top even when
the solid is occluded — instead of re-tinting and re-uploading all meshes.
- Hover / pick hit-testing scanned every triangle of every solid each move
(seconds on a heavy model). Add a 3D-AABB screen-rect broad phase
(MeshLodSet now carries z_aabb) and reuse the renderer's cached expanded mesh
set, so picking is O(solids) cheap projections plus the few solids actually
under the cursor.
- Block-internal hatch hit-testing exploded every INSERT on every hover.
Cache the result per geometry epoch and skip blocks that contain no hatch.
- Curved-surface (cone/sphere/torus) tessellation tolerance is now radius-
relative (CURVE_REL_TOL) so a cylinder's facet count is size-independent and
matches the circle/arc wire tessellation, instead of exploding on large radii.
Also adds docs/tessellation.md mapping every EntityType to its tessellation
path (truck B-rep vs truck curve topology vs direct).

3D solid / surface meshes were the last single-f32 path. truck's mesh
tessellation now returns a paired verts_low residual (TruckTessResult::Mesh,
polygon_to_result), MeshModel/MeshLodSet carry it, the model-space offset
and block-instance transforms reconstruct the f64 position and re-split it
after subtracting world_offset, MeshVertex gains position_low (location 3),
and mesh.wgsl reconstructs the eye-relative position. Native SAT / ACIS /
OBJ mesh paths default to a zero residual (no regression — they were never
sub-f32 precise).
With this every world-space pipeline (wire, hatch, image, face3d, mesh)
is full double-single relative-to-eye; large-coordinate jitter is gone.

Gate target-specific code so neither build warns about the other's items:
native-only helpers (view, window icon, file dialogs, file association, plugin
host/guard/registry, self-update) are cfg'd to non-wasm; the wasm-only font
fallback (script_of / cjk_lang / request) is cfg'd to wasm. Drop an unused mut,
allow the few genuinely-conditional dead items (mesh_click_hit, GPU layout
helpers, parity stubs), and gate the embedded PlotSettings-unrelated dead
constants. Both targets now build clean (only the unavoidable nom/quick-xml
future-incompat dependency notice remains).

Bump acadrust to pick up real ACIS body transforms (so moving/copying/
rotating a 3D solid relocates its geometry) and OCS-aware INSERT placement.
- body_transform: read the SAT transform record from its first 13 float
tokens instead of by raw index, which skipped the matrix because the
record leads with a book-keeping pointer — so the body placement was
silently ignored and solids never honored their stored transform.
- Insert grips: the grip lives in world space but insert_point is stored in
the block's OCS, so grip display and grip-drag now round-trip through the
OCS. A block whose extrusion normal isn't +Z no longer shows its grip in
the wrong place or drags along the wrong axes.

Build pierced planar faces (a wall with a window opening) as truck faces
with inner hole boundaries: collect every face loop (outer + holes), wind
each hole opposite the outer so try_attach_plane cuts it, and let truck
triangulate. Drop the back-face cull on the solid-mesh pipelines so faces
show regardless of the import's winding (the shader already lights
two-sided). Relies on the acadrust SatLoop next_loop fix that makes hole
loops reachable. (#123)

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.
