Bare `ZOOM` had no dispatch arm — only the sub-keyword forms (ZOOM EXTENTS/IN/OUT/WINDOW/…) were handled, so typing `ZOOM` fell through to an unknown-command error. It now starts the interactive window zoom. Add the missing Zoom Window ribbon button: the command existed but had no tool()/icon, so it was reachable only by typing. Wire it into View ▸ Navigate with a new dashed-rectangle magnifier icon. Closes #210 Co-Authored-By: Claude Opus 4.8 <[email protected]>
