Five chunks moved out of the 5965-line scene/mod.rs to live with the
entities they belong to:
- wide_lwpolyline_fills → entities/lwpolyline.rs::wide_fills
- wide_polyline2d_fills → entities/polyline.rs::wide_fills
- polyline_segment_fill → entities/common.rs (shared by both above)
- text_obb_corners_native + text_baseline_points + text_greek_obb_tris
→ entities/text_support.rs (handles Text/MText/Attribute alike)
- append_insert_attribute_wires → entities/insert.rs
Net: scene/mod.rs 5965 → 5404 lines (~560 lines extracted). Three
helpers in scene/render.rs / scene/block_cache.rs widened from
pub(super) to pub(crate) so the relocated functions can still reach
them. scene::entity_aabb also widened for the same reason.
scene::tessellate_entity_dim_text stays put — it's a thin wrapper
around the private tessellate_entity dispatcher and moving it would
require exposing tessellate_entity's full signature across the crate.

The trait isn't deprecating anything — it carries the path entities
take when they're not covered by the truck topology pipeline
(Viewport, Insert, Hatch outline, Ole2Frame). "Fallback" names the
purpose; "Legacy" implied retirement that isn't actually on the
roadmap.
Same rename for LegacyGeometry → FallbackGeometry,
legacy_geometry() → fallback_geometry().

Each entity's tessellation now lives alongside its definition in
entities/*.rs, attached to the entity type via a local trait:
LegacyTess — Viewport / Insert / Hatch / Ole2Frame
(fallback path for entities not on the truck pipeline)
LeaderTess — Leader
MultiLeaderTess — MultiLeader
DimensionTess — Dimension (carries its dim-only helpers too:
~1700 lines of dim_geometry, dim_text_*, format_*,
tolerance, suppression, etc.)
scene/tessellate.rs keeps only the cross-entity dispatcher plus the
shared dim machinery reused by leader/multileader/dimension
(ArrowKind, DimGeom, append_arrow, arrow_from_block, add_segment,
add_polyline, normalized_or, push_tri, color_or_inherit, entity_z,
offset_snap_pts). Cross-entity arc helpers + aci_to_rgba moved to
scene/tess_util.rs.
scene/tessellate.rs shrinks from ~3300 to 809 lines. Compile clean,
all 9 tests pass.
