bug(vscode): tool call and reply order can be incorrect

[qqqys]

Bug Report Draft

What happened?

In the VS Code extension, the order of tool-call cards and assistant replies is sometimes incorrect during a single turn. A tool call may appear before the related assistant text, or the final answer may be rendered in a confusing sequence after tool activity. This makes the conversation timeline hard to follow.

What did you expect to happen?

Tool calls and assistant replies should appear in the same chronological order in which they happen during the turn. The assistant text should stay visually aligned with the tool activity it triggered, so the full reply reads naturally from top to bottom.

Anything else we need to know?

• This appears to affect the VS Code IDE companion chat UI.
• The problem is most noticeable when one assistant turn includes both streamed text and one or more tool calls.
• If possible, include a short screen recording or screenshots showing the wrong ordering.
• If reproducible, add the exact prompt and whether the issue happens consistently or only sometimes.
