feat: add Cmd+, settings shortcut, fix keybindings.json array validation

- Add app:settings keybinding (Cmd+,) to open settings block
- Fix config editor rejecting keybindings.json save because it
  requires JSON objects — keybindings.json is an array by design.
  Added allowArray flag to ConfigFile type.
