Session title not working correctly since 0.15.15 #3451

Description

The session title functionality is broken since version 0.15.15. When using GLM 4.6, the session title disappears completely, and when using Gemini, the session title remains as a timestamp instead of using the first prompt as the title.

Expected behavior

The session title should be set to the content of the first prompt for all supported models (GLM 4.6, Gemini, etc.).

Additional context

This functionality worked correctly in versions on 0.15.14.

OpenCode version

0.15.17

Steps to reproduce

1. Start a new session using GLM 4.6
2. Send the first prompt
3. Observe that the session title is gone/missing on the top, and in the timeline.

1. Start a new session using Gemini
2. Send the first prompt
3. Observe that the session title remains as a timestamp instead of the first prompt content
