Valentin KleinandClaude Opus 5.5 a349e4925f Command line, ViewCube and UCS icon take the pointer; history window (F2) (#181)
Clicks on the command line's history, the UCS icon and the ViewCube ring fell
through to the drawing (picking objects or starting a selection window, or
entering a point during a command), the chevron did nothing, and the wheel over
the overlays zoomed the drawing. The ViewCube's Top face was a click-only
widget, so the canvas still counted as hovered underneath it (crosshair, wheel).

- Every overlay now registers a widget that senses clicks and drags, so egui
  hands the pointer to the overlay instead of the canvas.
- Command line: a click on the history lines or the chevron (now pointing up)
  opens a scrollable history window with the whole log; F2 and TEXTSCR open it
  too (`ui.toggle.history`, Window > Command History). Dragging the history's
  top edge sets how many lines show (`ui.cmdline.lines`, 0-12).
- ViewCube (new viewcube.rs): Top face and a Home button run `zoom.extents`;
  hover highlights; right-click menu (Home, Hide ViewCube). The compass ring
  says that the 2D plan view can't rotate (no view twist yet) instead of
  doing nothing.
- UCS icon and the WCS pill open the coordinate-system menu (World, Hide UCS
  Icon).
- Control channel: `ui.drag` (real press, move, release) and
  `cmdline.state` -> `historyExpanded`.
