The OCS arbitrary-axis algorithm crossed the normal with Wx=(1,0,0) in the
else branch, which collapses to zero for an X-aligned normal (e.g.
N=(-1,0,0)): the OCS axes became zero and every point mapped to the
origin. The resulting coincident points fed a NaN truck arc whose
parameter_division never converged, hanging the load on "Parsing
entities". Cross with Wz=(0,0,1) per the DXF spec. (#142)

Solids (meshes) now tint on rollover and selection: hover washes orange,
selection washes blue, with selection winning when both apply. Meshes
re-upload their tint when the highlight set changes, and the rollover pick
now also hits shaded solid bodies and hatches (mirroring the click-select
order: wire → hatch → block hatch → solid).
Wires get the same scheme: the selection xray overlay recolours selected
entities blue and the hovered entity orange (previously both blue). Drops
the now-unused highlight_handles union helper and its cache.

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.
