Enhance SCIPSymbolAnalyzer with external symbol import extraction

- Updated _organize_results to include scip_index for external symbol extraction.
- Added _extract_imports_from_external_symbols method to handle imports from SCIP index.
- Implemented framework name extraction from symbol strings.
- Classified external symbols into standard_library and third_party categories.
- Removed obsolete inspect_doc_symbols.py script.
- Updated version of code-index-mcp to 2.1.2 and added libclang dependency.
- Removed tree-sitter-c dependency from the project.
