feat: complete Phase 1 infrastructure setup
This commit completes the Phase 1 project infrastructure setup for DB-Syncer-Debezium, establishing CI/CD pipelines, code quality tools, logging framework, and comprehensive documentation. Changes include: GitHub Actions CI/CD Pipeline (#3): - Multi-JDK build matrix (Java 17, 21) - Automated unit and integration testing - Code quality checks (Checkstyle, SpotBugs) - JaCoCo test coverage reporting with Codecov integration - OWASP dependency vulnerability scanning - Artifact archival for test results and coverage reports - Docker build validation on main branch Code Formatting and Style Configuration (#5): - Checkstyle 10.15.0 with Google Java Style based rules - SpotBugs 4.8.3.1 for bug detection - JaCoCo 0.8.11 for code coverage (60% minimum) - Maven Formatter Plugin 2.23.0 - Failsafe plugin for integration tests - EditorConfig for consistent IDE settings - Checkstyle suppression rules for generated code Logback Logging Framework (#6): - Spring profile-based configuration (dev/prod) - Rolling file appenders with 100MB size limit - 30-day log retention policy - Separate error log files for production - Module-specific log levels and formats - Configured for all 6 modules (common, metadata-service, cli, connectors, transformations, monitoring) Architecture and Development Documentation (#4): - ARCHITECTURE.md with complete system design - Detailed architecture diagrams and data flow - Core component specifications and responsibilities - Database schema design for metadata storage - Technology stack rationale - Single and production deployment architectures - Security and performance optimization guidelines - DEVELOPMENT.md with comprehensive developer guide - Environment setup instructions - Maven build commands and workflow - Code style guidelines and best practices - Testing standards and debugging tips - Troubleshooting common issues 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
