[Feature Request] Add option to disable terminal title updates

Summary

Please add a configuration option to disable terminal title updates (\x1B]0;title\x07 OSC escape sequences).

Use Case

On Termux (Android terminal emulator), terminal title changes trigger a visual notification that appears at the bottom of the screen, directly over the input area. Since Claude Code updates the title when detecting new conversation topics, this causes constant visual disruption that makes it difficult to see what is being typed.

Current Behavior

Claude Code sets the terminal title:

1. At startup (process.title="claude")
2. When a new conversation topic is detected (via AI analysis)

The title is set using the OSC escape sequence \x1B]0;title\x07.

Requested Behavior

Add a configuration option (e.g., terminalTitle: "disabled" or disableTerminalTitle: true) to prevent Claude Code from writing title escape sequences.

This could be added to the existing config system accessible via /config.

Environment

• Platform: Termux (Android terminal emulator)
• The title update itself works correctly; the issue is that Termux's notification overlay interferes with usability

Workaround Attempted

There is currently no workaround. Setting TERM=dumb may help but degrades the entire terminal experience.

This is a Termux-specific UX issue, but having the option to disable title updates would benefit any terminal environment where title changes are disruptive.
