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/no-duplicates
+
+⚠️ This rule _warns_ in the following configs: ☑️ `recommended`, 🚸 `warnings`.
+
+🔧 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 -->
+
+Reports if a resolved path is imported more than once.
+
+ESLint core has a similar rule ([`no-duplicate-imports`](https://eslint.org/docs/rules/no-duplicate-imports)), but this version
+is different in two key ways:
+
+1. the paths in the source code don't have to exactly match, they just have to point to the same module on the filesystem. (i.e. `./foo` and `./foo.js`)
+2. this version distinguishes Flow `type` imports from standard imports. ([#334](https://github.com/import-js/eslint-plugin-import/pull/334))
+
+## Rule Details
+
+Valid:
+
+```js
+import SomeDefaultClass, * as names from './mod'
+// Flow `type` import from same module is fine
+import type SomeType from './mod'
+```
+
+...whereas here, both `./mod` imports will be reported:
+
+```js
+import SomeDefaultClass from './mod'
+
+// oops, some other import separated these lines
+import foo from './some-other-mod'
+
+import * as names from './mod'
+
+// will catch this too, assuming it is the same target module
+import { something } from './mod.js'
+```
+
+The motivation is that this is likely a result of two developers importing different
+names from the same module at different times (and potentially largely different
+locations in the file.) This rule brings both (or n-many) to attention.
+
+### Query Strings
+
+By default, this rule ignores query strings (i.e. paths followed by a question mark), and thus imports from `./mod?a` and `./mod?b` will be considered as duplicates. However you can use the option `considerQueryString` to handle them as different (primarily because browsers will resolve those imports differently).
+
+Config:
+
+```json
+"import/no-duplicates": ["error", {"considerQueryString": true}]
+```
+
+And then the following code becomes valid:
+
+```js
+import minifiedMod from './mod?minify'
+import noCommentsMod from './mod?comments=0'
+import originalMod from './mod'
+```
+
+It will still catch duplicates when using the same module and the exact same query string:
+
+```js
+import SomeDefaultClass from './mod?minify'
+
+// This is invalid, assuming `./mod` and `./mod.js` are the same target:
+import * from './mod.js?minify'
+```
+
+### Inline Type imports
+
+TypeScript 4.5 introduced a new [feature](https://devblogs.microsoft.com/typescript/announcing-typescript-4-5/#type-on-import-names) that allows mixing of named value and type imports. In order to support fixing to an inline type import when duplicate imports are detected, `prefer-inline` can be set to true.
+
+Config:
+
+```json
+"import/no-duplicates": ["error", {"prefer-inline": true}]
+```
+
+<!--tabs-->
+
+❌ Invalid `["error", {"prefer-inline": true}]`
+
+```js
+import { AValue, type AType } from './mama-mia'
+import type { BType } from './mama-mia'
+
+import { CValue } from './papa-mia'
+import type { CType } from './papa-mia'
+```
+
+✅ Valid with `["error", {"prefer-inline": true}]`
+
+```js
+import { AValue, type AType, type BType } from './mama-mia'
+
+import { CValue, type CType } from './papa-mia'
+```
+
+<!--tabs-->
+
+## When Not To Use It
+
+If the core ESLint version is good enough (i.e. you're _not_ using Flow and you _are_ using [`import/extensions`](./extensions.md)), keep it and don't use this.
+
+If you like to split up imports across lines or may need to import a default and a namespace,
+you may not want to enable this rule.
