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)

+## Threat Model for resolve (module path resolution library)
+
+### 1. Library Overview
+
+- **Library Name:** resolve
+- **Brief Description:** Implements Node.js `require.resolve()` algorithm for synchronous and asynchronous file path resolution. Used to locate modules and files in Node.js projects.
+- **Key Public APIs/Functions:** `resolve.sync()` / `resolve/sync`, `resolve()` / `resolve/async`
+
+### 2. Define Scope
+
+This threat model focuses on the core path resolution algorithm, including filesystem interaction, option handling, and cache management.
+
+### 3. Conceptual System Diagram
+
+```
+Caller Application → resolve(id, options) → Resolution Algorithm → File System
+                           │
+                           └→ Options Handling
+                           └→ Cache System
+```
+
+**Trust Boundaries:**
+- **Input module IDs:** May come from untrusted sources (user input, configuration)
+- **Filesystem access:** The library interacts with the filesystem to resolve paths
+- **Options:** Provided by the caller
+- **Cache:** Used to improve performance, but could be a vector for tampering or information disclosure if not handled securely
+
+### 4. Identify Assets
+
+- **Integrity of resolution output:** Ensure correct and safe file path matching.
+- **Confidentiality of configuration:** Prevent sensitive path information from being leaked.
+- **Availability/performance for host application:** Prevent crashes or resource exhaustion.
+- **Security of host application:** Prevent path traversal or unintended filesystem access.
+- **Reputation of library:** Maintain trust by avoiding supply chain attacks and vulnerabilities[1][3][4].
+
+### 5. Identify Threats
+
+| Component / API / Interaction                       | S  | T  | R  | I  | D  | E  |
+|-----------------------------------------------------|----|----|----|----|----|----|
+| Public API Call (`resolve/async`, `resolve/sync`)   | ✓  | ✓  | –  | ✓  | –  | –  |
+| Filesystem Access                                   | –  | ✓  | –  | ✓  | ✓  | –  |
+| Options Handling                                    | ✓  | ✓  | –  | ✓  | –  | –  |
+| Cache System                                        | –  | ✓  | –  | ✓  | –  | –  |
+
+**Key Threats:**
+- **Spoofing:** Malicious module IDs mimicking legitimate packages, or spoofing configuration options[1].
+- **Tampering:** Caller-provided paths altering resolution order, or cache tampering leading to incorrect results[1][4].
+- **Information Disclosure:** Error messages revealing filesystem structure or sensitive paths[1].
+- **Denial of Service:** Recursive or excessive resolution exhausting filesystem handles or causing application crashes[1].
+- **Path Traversal:** Malicious input allowing access to files outside the intended directory[4].
+
+### 6. Mitigation/Countermeasures
+
+| Threat Identified                          | Proposed Mitigation |
+|--------------------------------------------|---------------------|
+| Spoofing (malicious module IDs/config)     | Sanitize input IDs; validate against known patterns; restrict `basedir` to app-controlled paths[1][4]. |
+| Tampering (path traversal, cache)          | Validate input IDs for directory escapes; secure cache reads/writes; restrict cache to trusted sources[1][4]. |
+| Information Disclosure (error messages)    | Generic "not found" errors without internal paths; avoid exposing sensitive configuration in errors[1]. |
+| Denial of Service (resource exhaustion)    | Limit recursive resolution depth; implement timeout; monitor for excessive filesystem operations[1]. |
+
+### 7. Risk Ranking
+
+- **High:** Path traversal via malicious IDs (if not properly mitigated)
+- **Medium:** Cache tampering or spoofing (if cache is not secured)
+- **Low:** Information disclosure in errors (if error handling is generic)
+
+### 8. Next Steps & Review
+
+1. **Implement input sanitization for module IDs and configuration.**
+2. **Add resolution depth limiting and timeout.**
+3. **Audit cache handling for race conditions and tampering.**
+4. **Regularly review dependencies for vulnerabilities.**
+5. **Keep documentation and threat model up to date.**
+6. **Monitor for new threats as the ecosystem and library evolve[1][3].**
