Adds 11 tests for the vim mode surface: - /vim status reports without persisting - bare /vim toggles; on|off set explicitly; each persists to display.vim_mode - editing_mode is applied to a running Application in both directions - a missing Application is not fatal (toggle before the TUI starts) - invalid arguments leave state untouched and print usage - _vim_mode_label() maps vi input modes to NORMAL/INSERT/REPLACE and stays empty when disabled or before the app exists - the config default is off and /vim is registered with subcommands
