Remote-control agent sessions cannot be stopped from codex agents

Summary

When Remote Control is enabled, sessions started through Remote Control remain ready and selectable in codex agents, but cannot be ended from the UI.

Environment

• Codex CLI: 0.149.1
• macOS
• Shared local app-server daemon started with Remote Control enabled

Steps to reproduce

1. Start the local daemon with Remote Control enabled and start an agent/session through Remote Control.
2. Run codex agents.
3. Select a ready agent other than the one to retain.
4. Try the advertised Ctrl-X action shown in the footer as ctrl+x stop.
5. Also try entering the session and using Ctrl-C, d, or /exit.

Actual behavior

• Ctrl-X does nothing: the selection remains and the agent/session stays ready and selectable.
• Ctrl-C, d, and /exit do not terminate the session/agent.
• The session therefore appears unkillable through either the session UI or the agent command center.

Expected behavior

The documented Ctrl-X action should explicitly stop/end the selected agent, remove it from the active agent list, and cancel any active turn without affecting other agents or the shared Remote Control daemon.

Workaround

codex archive <session-id> removes a ready session from the active list, but it is a reversible archive operation rather than a true stop/cancel mechanism. It is not an adequate workaround for a working agent.

I reproduced the non-functional Ctrl-X behavior locally while preserving another working session.
