Module app 

ralph app ... command group for macOS GUI integration.

Responsibilities:

• Define clap structures for app-related commands (currently open).
• Route app subcommands to the command implementation layer (crate::commands::app).

Not handled here:

• Building or installing the SwiftUI app bundle (see apps/RalphMac/).
• Any queue/runner logic (Ralph remains CLI-first; the GUI shells out to the CLI).

Invariants/assumptions:

• ralph app open is macOS-only; non-macOS platforms return a clear error.
