[Refactor] Extract configuration, remove unnecessary code, and create development documentation

[freedeaths]

Description

The codebase needs refactoring to improve maintainability and developer experience. This involves extracting hardcoded configurations, cleaning up unnecessary code, and providing comprehensive documentation.

Tasks

Configuration Extraction

• Extract hardcoded values into configuration files
• Create environment-specific config files (development, production, etc.)
• Centralize API endpoints, UI settings, and feature flags
• Make configuration easily customizable for different deployments

Code Cleanup

• Remove dead code and unused imports
• Eliminate duplicate logic and consolidate similar functions
• Remove commented-out code blocks
• Clean up console.log statements and debug code
• Optimize imports and dependencies

Documentation

• Create comprehensive README with setup instructions
• Document API interfaces and data structures
• Add code comments for complex logic
• Create contributing guidelines
• Document configuration options and deployment procedures
• Add architecture overview and design decisions

Expected Outcomes

• Cleaner, more maintainable codebase
• Easier onboarding for new developers
• Configurable deployment options
• Better code organization and structure
• Comprehensive developer documentation

Priority

High - This will improve development velocity and code quality for future features.
