Replaces the binary Wireframe/Solid toggle with a 7-mode dropdown
that maps onto acadrust's `ViewportRenderMode` enum: Wireframe 2D /
Wireframe 3D / Hidden Line / Flat Shaded / Gouraud Shaded / Flat
Shaded + Edges / Gouraud Shaded + Edges. Per-tab state lives on
`DocumentTab::render_mode`; the old `SetWireframe` message forwards
to `SetRenderMode` so the ribbon + WIREFRAME / SOLID command line
keep working.
`scene::render::render_mode_flags()` translates the mode into three
pipeline-facing booleans (`face3d_fill`, `mesh_fill`,
`show_3d_edges`); `mesh_fill` / `show_3d_edges` are stubs that the
upcoming phases will consume. `Primitive` carries the derived
`view_wireframe` plus the two new fields through to `prepare()`.
`Pipeline::upload_face3d` takes a `wireframe_only` flag that drops
3DFACE quad fills (built from `key_vertices`) while keeping the
`all_wires.fill_tris` channel — that channel carries text-LOD greek
rectangles and PolyfaceMesh face triangles which must stay visible
in wireframe mode. 3DFACE edges stay on regardless of mode.
Solid3D mesh wireframe rendering, Hidden Line z-prepass, and Flat /
Gouraud shader uniforms come in phases 1–4.

Replace the flat fixed-length axis arrows with a proper 3D tripod:
- Axis lengths are proportional (longest fills UCS_ICON_LEN, shorter
axes stay foreshortened) giving real depth perception as the camera
rotates
- Draw order computed from NDC Z so back axes render behind front ones
- X / Y / Z labels rendered beyond each arrowhead tip
- All axes drawn at full opacity with solid filled arrowheads

- Hide OS crosshair and drawn crosshair when cursor is over ViewCube area
- Enhanced hover glow in WGSL shader (blue tint + brightness boost)
- Fixed region_centroids() Y-axis sign for all FRONT/BACK-related regions
- Swapped corner geometry assignments (TPF↔TBK, BTF↔BBK) to match
intended FRONT/BACK semantics (sy=-1 = FRONT, sy=+1 = BACK)
- Corrected all snap_angles: yaw_pitch_to_quat(0,0) places eye at -Y
(FRONT view), so FRONT=0 and BACK=PI — cascaded through edges/corners

Viewport right-click now shows a proper widget-based context menu:
- When a command is active: Cancel / Enter
- Otherwise: Repeat last commands, Delete/Move/Copy (if selected),
Select All, Zoom Extents
CONSTRUCTIONLINE added as an alias for XLINE (XL).
Canvas-drawn placeholder removed; context menu closes on Escape,
click-outside, or when any action is taken.

- snap/mod.rs: Snapper gains otrack_enabled, tracking_points, dwell state;
update_otrack_dwell() acquires a snap point after DWELL_THRESHOLD=4
consecutive moves near the same position; otrack_snap() returns an
H/V alignment snap position; clear_tracking() resets state on command end
- overlay.rs: selection_overlay accepts ost_points + cursor_screen;
draws light-blue dashed H/V lines from acquired points + small cross marker
- statusbar.rs: OTRACK pill (F11) added next to DYN
- view.rs: projects tracking_points to screen, passes to selection_overlay
- update.rs: calls update_otrack_dwell + otrack_snap in ViewportMove;
overrides effective point with OST alignment when no normal snap is active
- ROADMAP.md: Object Snap Tracking marked ✅

- overlay.rs: dynamic_input_overlay() canvas widget draws a semi-transparent
coordinate tooltip near the cursor; shows X/Y in absolute mode or
dist/angle relative to last_point when a command base point exists
- statusbar: DYN toggle pill with F12 tooltip (calls ToggleDynInput)
- app/mod.rs: dyn_input: bool field (default true), ToggleDynInput message
- view.rs: builds DYN label and pushes overlay into viewport_stack when
dyn_input=true and a command is active
- document.rs: last_cursor_screen: iced::Point — updated on every ViewportMove
- ROADMAP.md: Dynamic Input overlay 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 ✅.

Before layout completes the viewport bounds are 0×0, causing project_point3
to produce NaN/Inf coordinates which panicked in lyon_path assertions.
Added early-return when bounds < 10px, and finite checks on all projected
and derived coordinates before calling any canvas drawing functions.

Screen-space UCS icon drawn on the existing selection canvas overlay.
Axes are projected from world space so the icon rotates with the camera,
always showing the correct X/Y/Z orientation relative to the drawing plane.
Each axis has its canonical color (X=red, Y=green, Z=blue) with arrowheads.
Icon visibility controlled by show_ucs_icon flag (default on); toggled by
UCSICON ON/OFF command which also updates paper-space viewport entities.
