UE-MCP

""" Shared constants for UE-MCP. This module contains constants that are shared across the MCP server and the scripts executed in UE5's Python environment. IMPORTANT: These constants must be kept in sync with the corresponding values in extra/scripts/ue_mcp_capture/utils.py since scripts run in a separate Python environment (UE5's embedded Python).
