feat: add CCW Loop System for automated iterative workflow execution

Implements a complete loop execution system with multi-loop parallel support,
dashboard monitoring, and comprehensive security validation.

Core features:
- Loop orchestration engine (loop-manager, loop-state-manager)
- Multi-loop parallel execution with independent state management
- REST API endpoints for loop control (pause, resume, stop, retry)
- WebSocket real-time status updates
- Dashboard Loop Monitor view with live updates
- Security: path traversal protection and sandboxed JavaScript evaluation

Test coverage:
- 42 comprehensive tests covering multi-loop, API, WebSocket, security
- Security validation for success_condition injection attacks
- Edge case handling and end-to-end workflow tests
