**CLI Integration:** - Added --engine parameter to md-render command - Default engine selection: testdrive-jsui for edit/insert, standard for view - Graceful fallback to standard rendering when plugin unavailable - Engine validation and mode compatibility checking **Plugin Discovery:** - Enhanced RenderingEngineManager with builtin plugin registration - Automatic discovery and registration of testdrive-jsui engine - Support for both plugin system discovery and direct registration **Configuration Management:** - Production-ready RenderingConfig for CLI usage - Asset deployment to _markitect/plugins/ structure - Configurable asset base URLs and deployment strategies **Testing Infrastructure:** - Comprehensive test suite for plugin discovery - CLI integration testing without Click framework dependencies - Complete scenario testing (default, explicit, fallback, unknown engines) - Integration verification scripts **Documentation:** - Complete PLUGIN_SYSTEM.md documentation - Architecture overview and development workflows - JavaScript-first development guide - Asset management and deployment strategies - CLI usage examples and troubleshooting guide **Key Features:** - `markitect md-render --edit` now uses testdrive-jsui by default - `markitect md-render --engine testdrive-jsui --edit` for explicit selection - `markitect md-render --engine standard --edit` for legacy behavior - Automatic fallback with user-friendly error messages This completes the plugin infrastructure implementation, enabling independent JavaScript development with seamless CLI integration. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
