Multiple tool results render incorrectly after expanding output with Ctrl+O

[devkade]

What happened?

In the interactive TUI, expanding several completed tool results with Ctrl+O can render incomplete or mismatched content. Some entries remain as headers or error summaries, while another entry shows only a trailing portion of its result. The collapsed list renders normally; the problem appears after expansion.

Observed on macOS arm64.

Steps to reproduce

1. Start Senpi in interactive mode with extensions disabled.
2. Run a prompt that performs several tool calls, such as reading multiple files in parallel.
3. Wait until the calls complete in collapsed form.
4. Press Ctrl+O to expand tool output.
5. Inspect each tool header and its displayed result.

Expected behavior

Each completed tool call displays its own complete result, associated with the correct header, after expansion.
