feat: add refactored testdrive-jsui capability with consolidated architecture

Complete integration of refactored testdrive-jsui capability:

## Refactored Architecture
- js/ - All JavaScript source (controls, components, core)
- static/ - CSS, images, templates
- src/testdrive_jsui/ - Python package
- tests/ - Python tests

## Plugin Self-Declaration
- get_plugin_source_dir() - plugin declares own location
- get_asset_paths() - organized asset paths
- No hardcoded discovery logic

## Merged Content
- Baseline UI scaffold (tutorials, LICENSE, INTRODUCTION.md)
- Refactored capability implementation
- Comprehensive documentation

Ready for standalone use or integration with markitect.
