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 valid titles (`valid-title`)
+
+💼 This rule is enabled in the ✅ `recommended`
+[config](https://github.com/jest-community/eslint-plugin-jest/blob/main/README.md#shareable-configurations).
+
+🔧 This rule is automatically fixable by the
+[`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).
+
+<!-- end auto-generated rule header -->
+
+Checks that the title of Jest blocks are valid by ensuring that titles are:
+
+- not empty,
+- is a string,
+- not prefixed with their block name,
+- have no leading or trailing spaces
+
+## Rule details
+
+**emptyTitle**
+
+An empty title is not informative, and serves little purpose.
+
+Examples of **incorrect** code for this rule:
+
+```js
+describe('', () => {});
+describe('foo', () => {
+  it('', () => {});
+});
+it('', () => {});
+test('', () => {});
+xdescribe('', () => {});
+xit('', () => {});
+xtest('', () => {});
+```
+
+Examples of **correct** code for this rule:
+
+```js
+describe('foo', () => {});
+describe('foo', () => {
+  it('bar', () => {});
+});
+test('foo', () => {});
+it('foo', () => {});
+xdescribe('foo', () => {});
+xit('foo', () => {});
+xtest('foo', () => {});
+```
+
+**titleMustBeString**
+
+Titles for `describe`, `test`, and `it` blocks should always be a string; you
+can disable this with the `ignoreTypeOfDescribeName` and `ignoreTypeOfTestName`
+options.
+
+Examples of **incorrect** code for this rule:
+
+```js
+it(123, () => {});
+describe(String(/.+/), () => {});
+describe(myFunction, () => {});
+xdescribe(myFunction, () => {});
+describe(6, function () {});
+```
+
+Examples of **correct** code for this rule:
+
+```js
+it('is a string', () => {});
+test('is a string', () => {});
+xtest('is a string', () => {});
+describe('is a string', () => {});
+describe.skip('is a string', () => {});
+fdescribe('is a string', () => {});
+```
+
+Examples of **correct** code when `ignoreTypeOfDescribeName` is `true`:
+
+```js
+it('is a string', () => {});
+test('is a string', () => {});
+xtest('is a string', () => {});
+describe('is a string', () => {});
+describe.skip('is a string', () => {});
+fdescribe('is a string', () => {});
+
+describe(String(/.+/), () => {});
+describe(myFunction, () => {});
+xdescribe(myFunction, () => {});
+describe(6, function () {});
+```
+
+Examples of **correct** code when `ignoreTypeOfTestName` is `true`:
+
+```js
+const myTestName = 'is a string';
+
+it(String(/.+/), () => {});
+it(myFunction, () => {});
+it(myTestName, () => {});
+xit(myFunction, () => {});
+it(6, function () {});
+```
+
+**duplicatePrefix**
+
+A `describe` / `test` block should not start with `duplicatePrefix`
+
+Examples of **incorrect** code for this rule
+
+```js
+test('test foo', () => {});
+it('it foo', () => {});
+
+describe('foo', () => {
+  test('test bar', () => {});
+});
+
+describe('describe foo', () => {
+  test('bar', () => {});
+});
+```
+
+Examples of **correct** code for this rule
+
+```js
+test('foo', () => {});
+it('foo', () => {});
+
+describe('foo', () => {
+  test('bar', () => {});
+});
+```
+
+**accidentalSpace**
+
+A `describe` / `test` block should not contain accidentalSpace, but can be
+turned off via the `ignoreSpaces` option:
+
+Examples of **incorrect** code for this rule
+
+```js
+test(' foo', () => {});
+it(' foo', () => {});
+
+describe('foo', () => {
+  test(' bar', () => {});
+});
+
+describe(' foo', () => {
+  test('bar', () => {});
+});
+
+describe('foo  ', () => {
+  test('bar', () => {});
+});
+```
+
+Examples of **correct** code for this rule
+
+```js
+test('foo', () => {});
+it('foo', () => {});
+
+describe('foo', () => {
+  test('bar', () => {});
+});
+```
+
+## Options
+
+```ts
+interface Options {
+  ignoreSpaces?: boolean;
+  ignoreTypeOfDescribeName?: boolean;
+  disallowedWords?: string[];
+  mustNotMatch?: Partial<Record<'describe' | 'test' | 'it', string>> | string;
+  mustMatch?: Partial<Record<'describe' | 'test' | 'it', string>> | string;
+}
+```
+
+#### `ignoreSpaces`
+
+Default: `false`
+
+When enabled, the leading and trailing spaces won't be checked.
+
+#### `ignoreTypeOfDescribeName`
+
+Default: `false`
+
+When enabled, the type of the first argument to `describe` blocks won't be
+checked.
+
+#### `disallowedWords`
+
+Default: `[]`
+
+A string array of words that are not allowed to be used in test titles. Matching
+is not case-sensitive, and looks for complete words:
+
+Examples of **incorrect** code when using `disallowedWords`:
+
+```js
+// with disallowedWords: ['correct', 'all', 'every', 'properly']
+describe('the correct way to do things', () => {});
+it('has ALL the things', () => {});
+xdescribe('every single one of them', () => {});
+test(`that the value is set properly`, () => {});
+```
+
+Examples of **correct** code when using `disallowedWords`:
+
+```js
+// with disallowedWords: ['correct', 'all', 'every', 'properly']
+it('correctly sets the value', () => {});
+test('that everything is as it should be', () => {});
+describe('the proper way to handle things', () => {});
+```
+
+#### `mustMatch` & `mustNotMatch`
+
+Defaults: `{}`
+
+Allows enforcing that titles must match or must not match a given Regular
+Expression, with an optional message. An object can be provided to apply
+different Regular Expressions (with optional messages) to specific Jest test
+function groups (`describe`, `test`, and `it`).
+
+Examples of **incorrect** code when using `mustMatch`:
+
+```js
+// with mustMatch: '^that'
+describe('the correct way to do things', () => {});
+fit('this there!', () => {});
+
+// with mustMatch: { test: '^that' }
+describe('the tests that will be run', () => {});
+test('the stuff works', () => {});
+xtest('errors that are thrown have messages', () => {});
+```
+
+Examples of **correct** code when using `mustMatch`:
+
+```js
+// with mustMatch: '^that'
+describe('that thing that needs to be done', () => {});
+fit('that this there!', () => {});
+
+// with mustMatch: { test: '^that' }
+describe('the tests that will be run', () => {});
+test('that the stuff works', () => {});
+xtest('that errors that thrown have messages', () => {});
+```
+
+Optionally you can provide a custom message to show for a particular matcher by
+using a tuple at any level where you can provide a matcher:
+
+```js
+const prefixes = ['when', 'with', 'without', 'if', 'unless', 'for'];
+const prefixesList = prefixes.join('  - \n');
+
+module.exports = {
+  rules: {
+    'jest/valid-title': [
+      'error',
+      {
+        mustNotMatch: ['\\.$', 'Titles should not end with a full-stop'],
+        mustMatch: {
+          describe: [
+            new RegExp(`^(?:[A-Z]|\\b(${prefixes.join('|')})\\b`, 'u').source,
+            `Describe titles should either start with a capital letter or one of the following prefixes: ${prefixesList}`,
+          ],
+          test: [/[^A-Z]/u.source],
+          it: /[^A-Z]/u.source,
+        },
+      },
+    ],
+  },
+};
+```
