// Arbiter — centralized command registry bootstrap.
// Registers navigation + domain commands on the global ⌘K palette backend
// (Arbiter.CommandRegistry) at page load. Individual Platform components can
// still register their own context-specific commands via Arbiter.useCommand().
//
// Zero UX loss: this file only adds commands. The existing CommandPalette UI
// and ⌘K keybinding keep working unchanged; they simply gain more targets.
