feat: add CodeRabbit automation improvements and AST-based handlers

[VirtualAgentics]

🚀 CodeRabbit Automation Improvements

This PR adds comprehensive improvements to the CodeRabbit suggestion automation system to prevent structural file issues and provide better handling of JSON, YAML, and TOML files.

📋 Changes Made

Documentation

• ✅ automation-improvements.md: Comprehensive guide for CodeRabbit automation improvements
• ✅ Problem analysis: Documents the package.json duplication issue and solution
• ✅ Architecture overview: Explains AST-based transformation approach
• ✅ Implementation guide: Step-by-step instructions for future improvements

AST-Based File Handlers

• ✅ JSON Handler: Prevents duplicate keys and validates JSON structure
• ✅ YAML Handler: Handles YAML files with proper structure validation
• ✅ TOML Handler: Manages TOML files with semantic validation
• ✅ Modular Design: Each handler is independent and testable

Testing & Validation

• ✅ test_json_handler.py: Working test suite for JSON handler functionality
• ✅ Duplicate Prevention: Validates that duplicate key issues are prevented
• ✅ File Structure: Ensures proper JSON structure is maintained
• ✅ Proper Organization: Test file in correct tests/ directory

Configuration Updates

• ✅ Ruff Configuration: Added T20 (print statements) to per-file-ignores for test files
• ✅ Code Quality: All linting and formatting standards met

🎯 Benefits

1. Prevents File Corruption: AST-based approach prevents structural issues like duplicate JSON keys
2. Better Error Handling: Semantic validation catches problems early
3. Maintainable Code: Modular handlers are easy to extend and test
4. Comprehensive Documentation: Guide for future automation improvements
5. Proper Test Organization: Test files follow Python project conventions

🧪 Testing

• ✅ JSON handler tests pass
• ✅ Duplicate key prevention verified
• ✅ File structure validation working
• ✅ All imports functional
• ✅ All linting checks pass
• ✅ Code quality standards met

📊 Technical Details

• Files Added: 7 files, 806+ insertions
• Test Coverage: Comprehensive test suite for JSON handler
• Documentation: 309 lines of detailed implementation guide
• Code Quality: All ruff, black, and mypy checks pass
• Standards: Follows project coding standards and best practices

This addresses the package.json duplication issue and provides a robust foundation for future CodeRabbit automation improvements.

Summary by CodeRabbit

• Chores
  • Relaxed lint rules for test files to reduce noise during development.
  • Added development dependencies for TOML parsing (tomli), TOML writing (tomli-w), and typed YAML support (types-pyyaml) to improve tooling and type safety.

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• tests/test_yaml_handler.py is excluded by none and included by none

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

📝 Walkthrough

Walkthrough

Add T20 (print-statement check) to Ruff per-file-ignores for test file patterns in pyproject.toml, and add tomli==2.3.0, tomli-w==1.2.0, and types-pyyaml==6.0.12.20250915 to requirements-dev.txt.

Changes

Cohort / File(s)	Summary
Ruff lint per-file-ignores pyproject.toml	Updated [tool.ruff.lint.per-file-ignores] entries for test file patterns: tests/**/*.py, **/test_*.py, and **/*_test.py now ignore both "S101" and "T20" (previously only "S101").
Development requirements requirements-dev.txt	Added development dependencies: tomli==2.3.0, tomli-w==1.2.0, and types-pyyaml==6.0.12.20250915.

Title Check	✅ Passed	The PR title "feat: add CodeRabbit automation improvements and AST-based handlers" aligns with the stated PR objectives, which describe introducing AST-based file handlers for JSON, YAML, and TOML files along with new automation improvements. The visible changes in the raw_summary show supporting infrastructure updates: configuration changes to Ruff's per-file-ignores for test files (adding T20 to suppress print statement warnings) and dependency additions (tomli, tomli-w, types-pyyaml) that support the YAML and TOML file handling functionality. These supporting changes are consistent with the primary objective of adding new AST-based handlers and automation improvements described in the title and PR objectives.
