[Bug] Terminal setup fails in Windows Terminal with Shift+Enter shortcut configuration

Bug Description
/terminal-setup
⎿ Terminal setup cannot be run from windows-terminal.

This command configures a convenient Shift+Enter shortcut for multi-line prompts.
Note: You can already use backslash (\) + return to add newlines.

To set up the shortcut (optional):

1. Exit tmux/screen temporarily
2. Run /terminal-setup directly in one of these terminals:

• Windows: Windows Terminal
• IDE: VSCode, Cursor, Windsurf, Zed
• Other: Alacritty

1. Return to tmux/screen - settings will persist

Note: iTerm2, WezTerm, Ghostty, Kitty, and Warp support Shift+Enter natively.
