- Fix arrow-key nudge description: was "20px/100px" (wrong), now "10px/50px" (matches useKeyboardShortcuts)
- Add Cmd/Ctrl+Arrow resize shortcut row to dialog (missing since PR #192)
- Fix 3 tests in useKeyboardShortcuts.test.tsx that asserted shrink below min dimensions:
"resizes height down" expected height:100, clamped to 110 (node starts at minHeight)
"resizes width down" expected width:200, clamped to 210 (node starts at minWidth)
"2px step with Shift" expected height:108, clamped to 110 (minHeight wins)
All three tests updated to assert clamped values with explanatory comments.
