Manually renamed session titles get overwritten by auto-generated titles

Description

When using Claude Code (via web/mobile), I rename a session title to something meaningful (e.g., the project name) so I can identify which session belongs to which project. However, the title gets automatically overwritten/regenerated as the conversation continues, losing my custom name.

Steps to reproduce

1. Open a Claude Code session
2. Have a conversation (the platform auto-generates a title)
3. Manually rename the session title to something custom
4. Continue the conversation
5. The title gets overwritten by a new auto-generated title

Expected behavior

Once a user manually renames a session title, it should stay as-is and not be overwritten by auto-generated titles.

Why this matters

When working across multiple projects, session titles are the main way to identify which conversation belongs to which project. Auto-overwriting defeats the purpose of renaming.
