Bug: Shift+Enter not working in Cursor IDE #4

Problem

Shift+Enter shortcut does not work as expected when using core-cli in Cursor IDE's integrated terminal. Same result as with macOS Terminal.

Steps to Reproduce

1. Open Cursor IDE integrated terminal
2. Run any core-cli prompt
3. Attempt Shift+Enter for newline or separation
4. Expected: Insert newline or trigger appropriate CLI response
5. Actual: No effect or unexpected cursor movement

Acceptance Criteria

• Shift+Enter works for newlines or correct action in interactive prompts
• Consistent experience between standard macOS Terminal and Cursor IDE terminal
