C:/Program Files/Git/resume collapses final text response in focus mode

Description

When using /focus mode and then resuming a conversation with /resume, the final text response gets collapsed along with tool calls. Only the tool call summary line is shown (e.g., "Called 1 tool · 3 messages hidden (/focus to show)"), and the actual text reply is hidden.

Steps to reproduce

1. Enable /focus mode
2. Send a request that involves tool calls (e.g., a web search followed by a text summary)
3. Exit the conversation
4. Resume with /resume

Expected behavior

• Tool calls should be hidden (as per focus mode design)
• The final text response should be displayed normally

Actual behavior

• The entire response (including the final text reply) is collapsed into a single line: Called 1 tool · 3 messages hidden (/focus to show)
• The user cannot see the text summary without toggling focus mode off
