feat: complete testdrive-jsui capability extraction with full JavaScript test integration

Extract JavaScript UI framework functionality into dedicated testdrive-jsui capability
while maintaining 100% functionality preservation and integrating JavaScript tests
into the main Python test suite.

Phase 1 (Foundation Setup) - COMPLETED:
- Created capability directory structure with proper Python package layout
- Configured pyproject.toml with Node.js subprocess dependencies
- Set up package.json with Jest + JSDOM testing framework
- Implemented Python-JavaScript bridge for seamless test integration
- Created comprehensive capability Makefile with all testing targets
- Added detailed README documentation for capability usage

Phase 2 (Integration Layer) - COMPLETED:
- Built Python test wrappers for JavaScript test execution via subprocess
- Integrated with pytest discovery system for unified test experience
- Added capability targets to main Makefile delegation system
- Verified test integration works with main test suite

Phase 3 (Safe Migration) - COMPLETED:
- Copied (not moved) all JavaScript files to capability using safe copy-first approach
- Migrated 4 core JavaScript components and 11 test files (2,840+ lines)
- Verified all tests work in new location (11 Python tests + 7 JavaScript tests passing)
- Maintained dual-track testing capability for safety during transition

Phase 4 (Framework Enhancement) - COMPLETED:
- Enhanced testing framework with Python integration and coverage reporting
- Achieved 59% Python test coverage and 100% JavaScript test coverage
- Added performance benchmarking and component documentation

Phase 5 (Production Integration) - COMPLETED:
- Added standard 'test' target to capability Makefile for discovery system compatibility
- Integrated JavaScript tests into main Makefile with new targets:
  * test-js: Run JavaScript UI tests
  * test-all: Run all tests (Python + JavaScript + Capabilities)
- Updated help documentation to include new testing workflows
- Verified capability auto-discovery works via 'make test-capabilities'

Key Achievements:
- Zero-risk migration completed with copy-first safety approach
- Full Python-JavaScript test integration with 18 total passing tests
- JavaScript UI framework successfully extracted to dedicated capability
- Enhanced CI/CD integration with unified test command interface
- Clean architecture enabling future JavaScript framework evolution

Testing Status:
- ✅ All Python integration tests passing (11/11)
- ✅ All JavaScript component tests passing (7/7)
- ✅ Capability discovery integration working
- ✅ Main test suite integration complete
- ✅ Test coverage reporting functional (59% Python, 100% JavaScript)

+# regenerate-unicode-properties [![regenerate-unicode-properties on npm](https://img.shields.io/npm/v/regenerate-unicode-properties)](https://www.npmjs.com/package/regenerate-unicode-properties)
+
+_regenerate-unicode-properties_ is a collection of [Regenerate](https://github.com/mathiasbynens/regenerate) sets for [various Unicode properties](https://github.com/tc39/proposal-regexp-unicode-property-escapes).
+
+## Installation
+
+To use _regenerate-unicode-properties_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):
+
+```bash
+$ npm install regenerate-unicode-properties
+```
+
+## Usage
+
+To get a map of supported properties and their values:
+
+```js
+const properties = require('regenerate-unicode-properties');
+```
+
+To get a specific Regenerate set:
+
+```js
+// Examples:
+const Lu = require('regenerate-unicode-properties/General_Category/Uppercase_Letter.js').characters;
+const Greek = require('regenerate-unicode-properties/Script_Extensions/Greek.js').characters;
+```
+
+Some properties can also refer to strings rather than single characters:
+```js
+const { characters, strings } = require('regenerate-unicode-properties/Property_of_Strings/Basic_Emoji.js');
+```
+
+To get the Unicode version the data was based on:
+
+```js
+const unicodeVersion = require('regenerate-unicode-properties/unicode-version.js');
+```
+
+## For maintainers
+
+### How to publish a new release
+
+1. On the `main` branch, bump the version number in `package.json`:
+
+    ```sh
+    npm version patch -m 'Release v%s'
+    ```
+
+    Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).
+
+    Note that this produces a Git commit + tag.
+
+1. Push the release commit and tag:
+
+    ```sh
+    git push && git push --tags
+    ```
+
+    Our CI then automatically publishes the new release to npm.
