tegwick f331634673 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
