feat: implement plugin-based architecture with md- command prefixes - Issue #44
Complete migration of markdown commands to plugin-based architecture: ✅ Architecture Changes: - Created comprehensive MarkdownCommandsPlugin with md- prefixes - Migrated legacy commands: ingest → md-ingest, get → md-get, list → md-list - Leveraged existing CommandPlugin framework for consistency - Removed deprecated unprefixed commands from CLI ✅ Backward Compatibility: - Comprehensive bash aliases (aliases.sh) for smooth transition - Migration guide with detailed transition instructions - Convenience functions for common workflows ✅ Test Suite Updates: - Fixed 107+ core CLI tests to use new command structure - Updated all test files referencing old commands - Verified end-to-end functionality with complete test coverage ✅ Benefits Delivered: - Consistent command namespace (all commands now prefixed) - Modular plugin architecture enabling future extensions - Lazy loading capabilities for performance optimization - Clear separation of concerns for maintainability Cost: €0.15 for comprehensive architectural improvement 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
