feat: Add LLM-powered documentation automation workflow

[aryanranderiya]

Description

Create an intelligent GitHub Actions workflow that automatically updates documentation using LLM-powered analysis when code changes are merged to the main branch.

Requirements

Change Detection

• Use git diff to detect meaningful code or API changes
• Focus on changes that impact user-facing functionality or developer APIs
• Skip cosmetic changes like formatting or comments
• Analyze changes in Python and TypeScript files

LLM Integration

• Integrate with OpenAI or Claude API for intelligent documentation generation
• Use LLM to analyze code changes and determine documentation impact
• Generate or update relevant markdown files in README.md and docs/ directory
• Optionally update inline docstrings in changed Python and TypeScript files

Documentation Updates

• Update existing documentation sections that are affected by code changes
• Generate new documentation sections for new features or APIs
• Maintain consistent documentation style and structure
• Only commit changes when meaningful updates are detected

Workflow Configuration

• Trigger only on merge to main branch
• Make API provider configurable for future extensibility
• Support modular architecture for different LLM providers
• Include proper error handling and fallback mechanisms

Acceptance Criteria

• GitHub Actions workflow created for post-merge documentation updates
• Git diff analysis identifies meaningful code changes
• LLM API integration functional with configurable provider
• Documentation files updated automatically when relevant
• Inline docstrings updated for changed functions/classes
• Changes committed back to repository or PR created for review
• Workflow only runs on actual functional changes
• Modular design supports multiple LLM providers

Technical Considerations

• Secure API key management for LLM services
• Rate limiting and cost control for API calls
• Git configuration for automated commits
• Conflict resolution for concurrent documentation changes
• Rollback mechanism for incorrect automated updates
