Feature request: option to disable terminal tab title management

Problem

Claude Code actively sets the terminal tab title via OSC escape sequences, overriding any title set by shell hooks (zsh chpwd/precmd) or external scripts. There is no way to disable this behavior.

This is a problem for users who run multiple Claude Code sessions in different project directories simultaneously. All tabs show the same "claude" title, making it impossible to distinguish between projects.

Current behavior

• Shell-level tab title management (e.g., zsh chpwd hooks that set titles based on CWD) works correctly outside Claude Code
• Once Claude Code starts, it continuously overwrites the tab title
• terminalTitleFromRename: false in settings only affects /rename — Claude Code still manages the title through other mechanisms
• Ghostty's shell-integration-features = no-title is also bypassed since Claude Code sets titles directly, not through shell integration

Attempted workarounds (all failed or caused flickering)

1. SessionStart hook with OSC sequences → Claude Code overwrites immediately after
2. UserPromptSubmit hook → causes flickering as both Claude Code and the hook fight over the title
3. Direct write to /dev/ttysXXX → works for ~1 second, then overridden by Claude Code
4. Background loop re-setting title → works but causes constant flickering

Proposed solution

Add a setting like terminalTitle with options:

• true (default, current behavior)
• false — Claude Code does not touch the terminal title at all
• Or a terminalTitlePrefix option that prepends a user-defined string (e.g., project emoji) to Claude Code's title

This would allow users to manage tab titles themselves via shell hooks, terminal config, or wrapper scripts.

Use case

Running 5+ Claude Code tabs simultaneously for different projects (e.g., infrastructure, product development, client work). Each directory has a shell hook that sets a project-specific emoji + name as tab title. This works perfectly in regular terminal usage but breaks inside Claude Code.

Environment

• Terminal: Ghostty 1.2+
• Shell: zsh with custom chpwd hook for tab titles
• Claude Code: latest (MAX plan)
