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)

+# Enforce assertion to be made in a test body (`expect-expect`)
+
+⚠️ This rule _warns_ in the ✅ `recommended`
+[config](https://github.com/jest-community/eslint-plugin-jest/blob/main/README.md#shareable-configurations).
+
+<!-- end auto-generated rule header -->
+
+Ensure that there is at least one `expect` call made in a test.
+
+## Rule details
+
+This rule triggers when there is no call made to `expect` in a test, to prevent
+users from forgetting to add assertions.
+
+Examples of **incorrect** code for this rule:
+
+```js
+it('should be a test', () => {
+  console.log('no assertion');
+});
+test('should assert something', () => {});
+```
+
+Examples of **correct** code for this rule:
+
+```js
+it('should be a test', () => {
+  expect(true).toBeDefined();
+});
+it('should work with callbacks/async', () => {
+  somePromise().then(res => expect(res).toBe('passed'));
+});
+```
+
+## Options
+
+```json
+{
+  "jest/expect-expect": [
+    "error",
+    {
+      "assertFunctionNames": ["expect"],
+      "additionalTestBlockFunctions": []
+    }
+  ]
+}
+```
+
+### `assertFunctionNames`
+
+This array option specifies the names of functions that should be considered to
+be asserting functions. Function names can use wildcards i.e `request.*.expect`,
+`request.**.expect`, `request.*.expect*`
+
+Examples of **incorrect** code for the `{ "assertFunctionNames": ["expect"] }`
+option:
+
+```js
+/* eslint jest/expect-expect: ["error", { "assertFunctionNames": ["expect"] }] */
+
+import { expectSaga } from 'redux-saga-test-plan';
+import { addSaga } from '../src/sagas';
+
+test('returns sum', () => {
+  expectSaga(addSaga, 1, 1).returns(2).run();
+});
+```
+
+Examples of **correct** code for the
+`{ "assertFunctionNames": ["expect", "expectSaga"] }` option:
+
+```js
+/* eslint jest/expect-expect: ["error", { "assertFunctionNames": ["expect", "expectSaga"] }] */
+
+import { expectSaga } from 'redux-saga-test-plan';
+import { addSaga } from '../src/sagas';
+
+test('returns sum', () => {
+  expectSaga(addSaga, 1, 1).returns(2).run();
+});
+```
+
+Since the string is compiled into a regular expression, you'll need to escape
+special characters such as `$` with a double backslash:
+
+```js
+/* eslint jest/expect-expect: ["error", { "assertFunctionNames": ["expect\\$"] }] */
+
+it('is money-like', () => {
+  expect$(1.0);
+});
+```
+
+Examples of **correct** code for working with the HTTP assertions library
+[SuperTest](https://www.npmjs.com/package/supertest) with the
+`{ "assertFunctionNames": ["expect", "request.**.expect"] }` option:
+
+```js
+/* eslint jest/expect-expect: ["error", { "assertFunctionNames": ["expect", "request.**.expect"] }] */
+const request = require('supertest');
+const express = require('express');
+
+const app = express();
+
+describe('GET /user', function () {
+  it('responds with json', function (done) {
+    request(app).get('/user').expect('Content-Type', /json/).expect(200, done);
+  });
+});
+```
+
+### `additionalTestBlockFunctions`
+
+This array can be used to specify the names of functions that should also be
+treated as test blocks:
+
+```json
+{
+  "rules": {
+    "jest/expect-expect": [
+      "error",
+      { "additionalTestBlockFunctions": ["theoretically"] }
+    ]
+  }
+}
+```
+
+The following is _correct_ when using the above configuration:
+
+```js
+import theoretically from 'jest-theories';
+
+describe('NumberToLongString', () => {
+  const theories = [
+    { input: 100, expected: 'One hundred' },
+    { input: 1000, expected: 'One thousand' },
+    { input: 10000, expected: 'Ten thousand' },
+    { input: 100000, expected: 'One hundred thousand' },
+  ];
+
+  theoretically(
+    'the number {input} is correctly translated to string',
+    theories,
+    theory => {
+      const output = NumberToLongString(theory.input);
+      expect(output).toBe(theory.expected);
+    },
+  );
+});
+```
