agent_coder 6e70c7bd6a test(editor): cover refocusEditorAfterMenuClose guard (#269 review F1)
Unit-test the focus-restore guard: an external <input> active -> editor.view.focus
NOT called (deliberate move respected); a non-focusable element active -> focus
called once. Fake editor + fake timers (rAF via setTimeout stub); view.focus is a
spy. Regression lock for the guard that keeps focus out of the page-title input.

agent_coder 2b36997c63 fix(editor): restore editor focus after table menu closes so Ctrl+Z works (closes #269)
The row/column grip and cell-chevron menus are Mantine <Menu>s with
returnFocus:true whose targets live outside the editor's contenteditable. After
a menu action focus returns to that outside target, so ProseMirror's undo keymap
never sees Ctrl+Z until the user clicks back into a cell. Add
refocusEditorAfterMenuClose(editor): on the next frame (after Mantine's
returnFocus) restore editor focus via view.focus(), unless the user intentionally
moved to another input/editable. Wired into both onClose paths (the shared
row/column lifecycle hook + cell-chevron).
