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.

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.

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

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.

- Enforce status.locked in pan_active_viewport and zoom_active_viewport:
locked viewports now reject pan/zoom inputs entirely
- Add perspective, render_mode, shade_plot_mode, hide_plot, ucs_icon_visible
fields to the viewport property panel with appropriate pickers/toggles
- Add VPORTS command: lists all user viewports in the current layout
(id, size, position, scale, on/locked state) in the command line
- Add VPLAYER command: per-viewport layer freeze/thaw from the command line
(F <layer> to freeze, T <layer> to thaw, Enter to exit)
- Add CmdResult::VpLayerUpdate variant and its handler in apply_cmd_result

Each command implementation is now in the same file as its ribbon
tool definition. Groups moved to a dedicated groups/ toolbar folder.
