[BUG] `-n` / `--name` flag does not update Windows Terminal tab title on Windows

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

The -n / --name flag is documented as setting "a display name for this session (shown in /resume and terminal title)". While the session name is correctly
saved and visible in /resume, the terminal tab title is not updated on Windows Terminal.

## Environment

• Claude Code version: 2.1.76
• OS: Windows 11 Pro 10.0.26200
• Terminal: Windows Terminal
• Shell: bash

What Should Happen?

## Expected Behavior

The Windows Terminal tab title should update to my-session-name (or include it), as documented.

## Actual Behavior

The terminal tab title stays as the default shell path.

Additional Information

• The -n flag correctly sets the display name — it shows up in the /resume picker.
• The title CMD command (title my-session-name) does change the Windows Terminal tab title, but gets overwritten once Claude Code's interactive REPL starts,

suggesting Claude Code resets the terminal title on startup.
