Subject: [PATCH 1/2] test: expand test coverage with 70 new test cases

Add comprehensive test suites for 3 additional core modules:
- test_extract_docs.py (26 tests, 628 lines) - JSDoc/Python docstring extraction
- test_generate_diagram.py (20 tests, 459 lines) - Mermaid diagram generation
- test_init_wiki.py (24 tests, 224 lines) - Wiki initialization

Total: 94 test cases across 6 modules, 1,676 lines of test code
Test coverage increased from ~30% to ~75% (6/8 core modules)
