• Improved error messaging to clearly indicate Python 3.11+ requirement for in-memory server functionality

Detailed Changes

CLI Dev Command

• Added Python version check in the dev command that displays a helpful message when users try to use the in-memory server feature with Python versions below 3.11
• The error message now explicitly states the Python version requirement (3.11+), shows the user's current Python version, and provides guidance on upgrading before installing the in-memory server extension
