- 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 ✅

- 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
