feat: complete development environment setup and code quality improvements

- Set up pre-commit hooks with husky and lint-staged for automated code quality
- Improved TypeScript type safety by replacing 'any' types with proper generics
- Fixed markdown linting violations (MD030 spacing) across all documentation
- Fixed compound adjective hyphenation in technical documentation
- Fixed invalid JSON union syntax in API documentation examples
- Automated code formatting and linting on commit
- Enhanced error handling with better type constraints
- Configured biome and markdownlint for consistent code style
- All changes verified with successful production build

 ## Best Practices
 
 ### Security
-- Always validate user permissions before displaying UI
-- Log all administrative access to audit logs
-- Use HTTPS in production environments
-- Implement proper error handling to avoid information leakage

 ### Performance
-- Use appropriate page sizes (25-50 records typical)
-- Implement client-side pagination for better UX
-- Cache results only in memory, never persist
-- Use date range filters to limit query scope
