- renderer: render_architecture_md accepts Config, uses project name and current date
- renderer: generate real Python usage examples from analyzed symbols
- writer: skip writing files when content unchanged (optimization)
- cli: add --dry-run flag to generate command (lists files without writing)
- cli: add verbose logging for file/module/symbol generation progress
- Test config loading and validation on test-project
- Test scanning Python files from test-project
- Test cycle detection with known cyclic and acyclic graphs
- Test renderer output generation
- Test duration and file size parsing
