Ctrl+O to expand execution re-triggers answered /btw query

Bug description

Pressing Ctrl+O to expand a running execution's details re-triggers a previously answered /btw query.

Steps to reproduce

1. Start a long-running execution in Claude Code
2. While the execution is running, use /btw to ask a side question
3. Wait for Claude to answer the /btw question
4. Press Ctrl+O to expand/view details of the running execution
5. The /btw query gets re-triggered and re-sent to Claude

Expected behavior

Pressing Ctrl+O should only expand the execution details without re-triggering any previously answered /btw queries.

Actual behavior

The /btw query is re-executed after pressing Ctrl+O, causing a duplicate response cycle.
