- src/modules/insert/wblock.rs: extract_block_to_doc() copies a named
block's entities into a fresh CadDocument; extract_entities_to_doc()
does the same for a selection set; layer definitions are carried over
- WBLOCK <name> writes the named block; WBLOCK * writes selected entities
- WblockSave / WblockSaveResult messages drive the async save-dialog flow
- ROADMAP.md: 1.10 WBLOCK marked ✅

Grid snap (F9):
• snap spacing now tracks the visible grid zoom level — computed via
compute_grid_step() (same adaptive pow-of-5 logic as draw_grid),
updated on every ViewportMove so zooming in/out keeps snap aligned
with the grid lines on screen
Polar tracking (F10):
• configurable angle increment stored in polar_increment_deg (default 45°)
• right-click the POLAR pill to cycle through 15 → 30 → 45 → 90°
• pill label shows current angle ("POLAR 45°")
• visual guide line: while drawing with polar on, a dashed cyan line is
drawn from last_point along the snapped direction across the viewport
• SetPolarAngle message + handler; all polar_constrain() calls use the
stored increment instead of the hardcoded 45°
ROADMAP updated: Grid snap and Polar tracking marked ✅.

Both commands detect which terminal segment/vertex is nearest to the
pick point, compute the new endpoint along the segment direction, and
move only that terminal vertex — preserving all other vertices and bulge
values intact. ROADMAP updated: EXTEND and LENGTHEN marked ✅.

Add shared spline_ops module with:
- spline_to_bspline / bspline_to_spline: acadrust ↔ truck BSplineCurve conversion
- spline_sample_xy: sample DXF-XY projection at N+1 points with parameters
- spline_nearest_t: nearest-parameter search via coarse+bisection
- spline_pts_wire: world-space wire points for WireModel preview
TRIM: Spline entities can now be used as cutting boundaries (Geo::Spline
sampled into polyline segments) and as entities being trimmed; uses
BSplineCurve::cut() to produce surviving pieces.
EXTEND: extend_spline() shoots a tangent ray from the nearest endpoint
and appends a control point at the first boundary hit.
OFFSET: offset_spline() offsets each sample point along the local
perpendicular normal and rebuilds a new spline from the offset control pts.
BREAK: break_spline() uses spline_nearest_t() + BSplineCurve::cut() to
split the spline at one or two click points.
LENGTHEN: lengthen_spline() uses numerical arc-length integration +
bisection to cut the spline at the parameter corresponding to the new
requested length.

Decomposes Dimension (Linear, Aligned, Radius, Diameter, Angular2Ln,
Angular3Pt, Ordinate) into constituent Lines (extension lines, dimension
line) plus a Text entity for the dimension label value.

Replaced the simplified MOVE-based STRETCH with a real crossing-window
implementation. Workflow: pick two crossing-window corners, then base+target
points. Only vertices/endpoints inside the window are translated:
- Line: moves start/end independently
- LwPolyline/Polyline: moves individual vertices inside window
- Arc/Circle/Ellipse: moves whole entity if center is inside
- Insert/Text/MText: moves if insertion point is inside

Mark as done: Named Views, DDEDIT, HATCHEDIT, MASSPROP, FILLET Arc support.
Update priority list to reflect remaining work.

Add HATCHEDIT (HE alias) command. Works on pre-selected hatch or via
entity pick. Accepts text options: P <pattern>, S <scale>, A <angle>.
Enter applies changes; rebuilds hatch entity and GPU model via add_hatch.

Add DDEDIT (ED alias) command that edits Text/MText/Attribute entities
in-place via the command line. Double-clicking a text entity in model space
now auto-launches DDEDIT for that entity. Supports Text, MText,
AttributeDefinition, and AttributeEntity types.

Computes mass properties for selected entities and prints results to the
command line. Supports: Circle (area+perimeter), Arc (sector area+arc length),
Line (length), LwPolyline (shoelace area+perimeter+centroid), Ellipse
(numerical 256-pt integration for area and arc length).

Extended FilletCommand and ChamferCommand to accept Lines and Arcs as
first/second entity. Added fillet_line_arc() and fillet_arc_arc()
geometry functions that find a tangent fillet circle between the two
entities, trim each to the tangent point, and insert the fillet arc.
r=0 case trims/extends to the nearest intersection without inserting an arc.
