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)

+# import/namespace
+
+💼 This rule is enabled in the following configs: ❗ `errors`, ☑️ `recommended`.
+
+<!-- end auto-generated rule header -->
+
+Enforces names exist at the time they are dereferenced, when imported as a full namespace (i.e. `import * as foo from './foo'; foo.bar();` will report if `bar` is not exported by `./foo`.).
+
+Will report at the import declaration if there are _no_ exported names found.
+
+Also, will report for computed references (i.e. `foo["bar"]()`).
+
+Reports on assignment to a member of an imported namespace.
+
+Note: for packages, the plugin will find exported names
+from [`jsnext:main`], if present in `package.json`.
+Redux's npm module includes this key, and thereby is lintable, for example.
+
+A module path that is [ignored] or not [unambiguously an ES module] will not be reported when imported.

+
+## Rule Details
+
+Currently, this rule does not check for possible
+redefinition of the namespace in an intermediate scope. Adherence to the ESLint
+`no-shadow` rule for namespaces will prevent this from being a problem.
+
+For [ES7], reports if an exported namespace would be empty (no names exported from the referenced module.)
+
+Given:
+
+```js
+// @module ./named-exports
+export const a = 1
+const b = 2
+export { b }
+
+const c = 3
+export { c as d }
+
+export class ExportedClass { }
+
+// ES7
+export * as deep from './deep'
+```
+
+and:
+
+```js
+// @module ./deep
+export const e = "MC2"
+```
+
+See what is valid and reported:
+
+```js
+// @module ./foo
+import * as names from './named-exports'
+
+function great() {
+  return names.a + names.b  // so great https://youtu.be/ei7mb8UxEl8
+}
+
+function notGreat() {
+  doSomethingWith(names.c) // Reported: 'c' not found in imported namespace 'names'.
+
+  const { a, b, c } = names // also reported, only for 'c'
+}
+
+// also tunnels through re-exported namespaces!
+function deepTrouble() {
+  doSomethingWith(names.deep.e) // fine
+  doSomethingWith(names.deep.f) // Reported: 'f' not found in deeply imported namespace 'names.deep'.
+}
+
+```
+
+### Options
+
+#### `allowComputed`
+
+Defaults to `false`. When false, will report the following:
+
+```js
+/*eslint import/namespace: [2, { allowComputed: false }]*/
+import * as a from './a'
+
+function f(x) {
+  return a[x] // Unable to validate computed reference to imported namespace 'a'.
+}
+```
+
+When set to `true`, the above computed namespace member reference is allowed, but
+still can't be statically analyzed any further.
