- Add `active_ucs: Option<Ucs>` per-tab state to DocumentTab
- Add `ucs_to_wcs`, `wcs_to_ucs`, `ucs_z_axis`, `ucs_rotated_z` helpers
- Add `Camera::pick_on_plane` for ray–plane intersection against any plane
- Mouse picks project onto the active UCS XY plane instead of world XY
- Typed coordinates are converted from UCS space to WCS before dispatch
- UCS command now really activates/deactivates a UCS:
- `UCS W` resets to WCS (clears active_ucs)
- `UCS <name>` activates a named UCS
- `UCS SAVE <name>` saves the current active UCS
- `UCS ORIGIN x,y,z` shifts origin (in current UCS space)
- `UCS X/Y/Z <angle>` rotates the UCS around its own axes

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.

DIMDIAMETER: 3-click flow (center → arc point → text position) → DimensionDiameter.
Previews the diameter chord line.

ZOOM ALL (ZA) — fit all entities (alias for ZOOM EXTENTS)
ZOOM SCALE <n> (ZS) — set zoom factor (1/n multiplied to camera distance)

QSELECT TYPE <type> — select all entities of given type (e.g. LINE, CIRCLE)
QSELECT LAYER <name> — select all entities on the given layer
QSELECT COLOR <n|BYLAYER> — select all entities with given color index
QSELECT LINETYPE <name> — select all entities with given linetype
Deselects current selection and replaces with matched entities.

Entity pick → text input subcommands:
C / CLOSE → set closed flag
O / OPEN → clear closed flag
W <value> → set uniform width on LwPolyline vertices
X / EXIT → cancel
Command stays active after each op (CmdResult::PeditOp) for multiple edits.
Supports LwPolyline and Polyline2D.

Pick vertices, Enter to finish (≥2 pts). Text input while picking:
C / CLOSE → close and commit (≥3 pts)
S <value> → set scale factor (default 1.0)
S alone → prompt for scale then continue
Uses acadrust MLine::from_points / closed_from_points + scale_factor field.

Status bar: shows "N VP" pill (with tooltip) when in a paper layout that has
user viewports (id > 1). New Scene::viewport_count() method.
REVCLOUD: closed LwPolyline with arc bumps (bulge = 0.5) along each edge.
Click polygon corners, Enter to close into a revision cloud shape.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Pick polygon corners, Enter to close. Each edge is subdivided into arc
bumps (bulge = 0.5 ≈ 53° arcs). Result is a closed LwPolyline.
Arc bump length defaults to 1.0 drawing units.

Options via text input after entity pick:
DE <delta> — extend by delta (negative trims)
TO <total> — set absolute total length / arc length
P <percent> — scale by percentage
<number> — plain number treated as DE delta
Closest end to pick point is modified. Uses CmdResult::LengthenEntity.

Selection-gathering mode: select objects, press Enter to apply.
- Lines: checks collinearity + no-gap, merges into single line span
- Arcs: checks same center/radius + contiguous angles, merges to Arc or Circle
- Uses CmdResult::JoinEntities; geometry computed in cmd_result from document

3-step interactive flow:
1. Entity pick (first break point recorded at click location)
2. Optional first point refinement
3. Second break point → CmdResult::BreakEntity applied in cmd_result
Geometry:
- Line: project p1/p2 onto line parameter space → two line fragments
- Arc: project p1/p2 to arc angles → trim CCW from p1 to p2
- Circle: same as Arc, converts Circle → Arc
- LwPolyline: nearest-vertex split → two polyline fragments
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add three classic CAD measurement commands:
- DIST (DI): two-point pick → distance, angle, delta XYZ
- ID: one-point pick → coordinates
- AREA: multi-point polygon pick (Enter to close) → area + perimeter
New CmdResult::Measurement(String) variant ends active command and
prints result to command line without modifying the document.

- mline.rs: MLine renders center spine + two parallel offset lines at
±scale/2 using the vertex miter directions; vertex grips; scale,
closed and style-name properties
- tolerance.rs: Tolerance renders the GDT text string via font
tessellation at insertion_point with rotation from direction vector;
insertion grip and position properties
- properties.rs: Dimension entity's style_name EditText is upgraded to
a Choice dropdown when document.dim_styles is non-empty, enabling
point-and-click DimStyle assignment without a separate panel

- properties.rs: inject 'UCS Name' Choice property for viewports when
document.ucss is non-empty; resolves current handle to display name
- update.rs: intercept PropGeomChoiceChanged for 'vp_ucs_name'; clones
UCS origin/x_axis/y_axis into viewport and sets ucs_handle — no
trait signature change required
