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

 ## Monitoring Checklist
 
-- [ ] Check Neon dashboard for connection spikes
-- [ ] Monitor scheduler execution times
-- [ ] Review error logs for connection patterns
-- [ ] Test health endpoint regularly
-- [ ] Set up alerts for connection failures
