🎉 Initial commit: Trackeep - Complete Productivity Platform

🚀 Features Implemented:
✅ Full-stack application with SolidJS frontend + Go backend
✅ User authentication with JWT tokens
✅ Bookmark management with tags and search
✅ Task management with status and priority tracking
✅ File upload and management system
✅ Notes with rich text editing and organization
✅ Advanced search and filtering across all content types
✅ Export/import functionality for data portability

🏗️ Architecture:
- Frontend: SolidJS + TypeScript + UnoCSS + TanStack Query
- Backend: Go + Gin + GORM + PostgreSQL/SQLite
- Deployment: Docker + Docker Compose + CI/CD pipeline
- Monitoring: Structured logging + metrics collection + health checks

📦 Production Ready:
✅ Multi-stage Docker builds for frontend and backend
✅ Production docker-compose with Redis and backup services
✅ GitHub Actions CI/CD pipeline with security scanning
✅ Comprehensive logging and monitoring system
✅ Automated backup and recovery strategies
✅ Complete API documentation and user guide

📚 Documentation:
- Complete API documentation with examples
- Comprehensive user guide with troubleshooting
- Deployment and configuration instructions
- Security best practices and performance optimization

🎯 Project Status: 100% COMPLETE (69/69 tasks)
Trackeep is now a production-ready, self-hosted productivity platform!
