VSCode: Conversation titles now use last words instead of first message — breaks searchability

Problem

Recent update changed how conversations are titled in the Past Conversations tab in VSCode. Previously, conversations were named using the first line/words of the opening message. Now they appear to use the last few words of the most recent message.

This is a significant regression for searchability.

Use Case

I work Datadog support tickets daily and always start conversations with the ticket number (e.g., "2532622"). Under the old behavior, I could search Past Conversations by ticket number and instantly find the relevant session. Now every conversation is titled with whatever I happened to say last, which is essentially random and unsearchable.

Impact

• Search is broken for any workflow that relies on the first message as an identifier
• Manual renaming is a workaround but adds friction to every single conversation
• Conversations that were previously easy to find are now indistinguishable from each other

Expected Behavior

Conversation titles should use the first line or opening words of the first message in the conversation, as they did previously. This preserves the user's intentional framing of what the conversation is about.
