/agents command not available in desktop app

Bug report

Environment: Claude Code desktop app (macOS)

Description:
The /agents slash command (and other terminal dialog commands such as /permissions, /config, /doctor, /hooks) are not available in the desktop app. Typing /agents returns:

/agents isn't available in this environment.

Expected behavior:
These commands should work in the desktop app just as they do in the interactive CLI terminal (claude command).

Actual behavior:
The commands are silently blocked with no alternative provided. The desktop app has no other UI for managing agents, permissions, hooks, etc.

Suggested fix:
Either (a) implement equivalent GUI panels for these commands in the desktop app, or (b) open the interactive terminal dialog within the app window.
