fix Windows cp1252 crash, str.parent crash, mcp error message, god_nodes relative import

- Replace non-ASCII → with -> in __main__.py print statements (#992)
- Coerce paths to Path objects at extract() entry to fix str.parent crash (#988)
- Fix serve.py ImportError to recommend graphifyy[mcp] extra (#967)
- Change relative import in _tool_god_nodes to absolute to fix script invocation (#966)
