[FEATURE] Implement automated code documentation extraction and integration

[najeed]

Is your feature request related to a problem? Please describe.
With new source files being added regularly, manually documenting code modules, classes, and functions is becoming time-consuming and error-prone. Documentation often lags behind code changes, leading to outdated or missing API documentation.

Describe the solution you'd like
An automated code documentation extraction system that:

1. Automated API Documentation

   • Extract docstrings from all Python modules
   • Generate formatted API reference pages
   • Create cross-references between modules
   • Include usage examples from docstrings

2. Code Analysis and Documentation

   • Generate module dependency graphs
   • Extract and document public interfaces
   • Identify and document configuration options
   • Create class hierarchy documentation

3. Integration Pipeline

   • Integrate with Issue [DOCS] [GOOD FIRST ISSUE] Add comprehensive API documentation for eval_runner module #1 documentation generation
   • Update documentation on code changes
   • Validate documentation completeness
   • Generate change logs for API modifications

Implementation Approach

# Code documentation extraction
python scripts/extract_code_docs.py --module eval_runner
python scripts/extract_code_docs.py --all-modules
python scripts/generate_api_reference.py

# Integration with main documentation
python scripts/integrate_docs.py --code-docs --guides-docs

Expected Output

│   ├── eval_runner.md           # Main module documentation
│   ├── agents.md                # Agent interfaces

Technical Requirements

• Python AST parsing for code analysis
• Sphinx-style docstring parsing
• Markdown generation with cross-references
• Integration with existing documentation workflow
• Git integration for change detection

Acceptance Criteria

• Automated extraction of all public APIs
• Formatted API reference documentation
• Cross-references between related modules
• Integration with main documentation system
• CI/CD pipeline updates docs automatically
• Validation of documentation completeness
• Change detection and incremental updates

Benefits

• Always current API documentation
• Reduced manual documentation burden
• Consistent formatting and structure
• Better discoverability of APIs
• Automated validation of documentation completeness

Additional Context
This complements Issue #1 by focusing specifically on code documentation extraction, while Issue #1 handles higher-level guide generation.

Estimated Effort

• Medium (1 week)

Dependencies

• Issue [DOCS] [GOOD FIRST ISSUE] Add comprehensive API documentation for eval_runner module #1 (Documentation generation system)
• Python code analysis libraries
• Documentation templating system
