fix: Complete RLM system improvements and error fixes

- Add mock mode to ClaudeCodeSubagentClient with realistic test responses
- Fix test generation node initialization (ensure children array exists)
- Remove dashboard auto-launch to prevent startup errors
- Change schema creation warnings to debug level
- Add comprehensive mock responses for all subagent types

RLM orchestrator now fully functional with:
- Proper mock subagent execution
- Multi-stage review with quality thresholds
- Test generation and improvement cycles
- Clean error handling and retries
- Complete execution summaries with metrics

+# API Endpoint Feature
+
+Create a REST API endpoint for user management with the following operations:
+- GET /users - List all users
+- GET /users/:id - Get user by ID  
+- POST /users - Create new user
+- PUT /users/:id - Update user
+- DELETE /users/:id - Delete user
+
+Requirements:
+- Use Express.js
+- Include input validation
+- Add error handling
+- Return appropriate HTTP status codes
+- Use TypeScript
