- Open and New folder disable while a path draft is uncommitted: targetPath
still names the previous selection/listing, and committing against it
while a different path shows in the header adopts the wrong directory.
- The Miller columns keep their own row so a status/error line renders below
them inside the card instead of competing as a third flex item the dialog
clips off-screen.
- Both text inputs (path editor, folder name) carry the IME composition
guard the workspace-name inputs already had: a composing Enter confirms
the candidate, never submits.
