• Duplicate and copy/paste
  • Rotate structures (not only preview)
  • Nudge with arrow keys (both on preview and placed structures)

Summary: Add power-user shortcuts: duplicate/copy-paste, nudge selection, rotate placed structures.
Notes:
  • Current shortcuts cover tool switching, zoom, undo/redo, and preview rotation.
  • No copy/paste/duplicate, no arrow-key nudge, and no rotate for already-placed structures.
  • State already supports multi-select + move; keyboard can build on that + add rotate/duplicate actions with collision/bounds checks.
