What issue are you seeing?

Description:
When dragging the Codex tooling icon from the left pane to the right pane (or vice-versa), any active Codex chat session is cancelled. The in-progress conversation and its state are lost without warning.

Actual behavior:
The active chat is terminated and all progress is lost.

Impact:
This can be frustrating during longer or more complex Codex runs, as it causes accidental loss of work due to a purely UI-level action.

What steps can reproduce the bug?

Steps to reproduce:

1. Start a Codex chat and wait for it to generate or reason.
2. Drag the Codex tooling icon from the left pane to the right pane (or the opposite).
3. Observe that the chat is cancelled and progress is discarded.

What is the expected behavior?

Repositioning the Codex tooling UI should not interrupt or reset an active chat session.
