unclecode 91f7b9d129 feat(docker): add multi-container cluster deployment with CLI management ...

Add comprehensive Docker cluster orchestration with horizontal scaling support.

CLI Commands:
- crwl server start/stop/restart/status/scale/logs
- Auto-detection: Single (N=1) → Swarm (N>1) → Compose (N>1 fallback)
- Support for 1-100 container replicas with zero-downtime scaling

Infrastructure:
- Nginx load balancing (round-robin API, sticky sessions monitoring)
- Redis-based container discovery via heartbeats (30s interval)
- Real-time monitoring dashboard with cluster-wide visibility
- WebSocket aggregation from all containers

Security & Stability Fixes (12 critical issues):
- Add timeout protection to browser pool locks (prevent deadlocks)
- Implement Redis retry logic with exponential backoff
- Add container ID validation (prevent Redis key injection)
- Add CLI input sanitization (prevent shell injection)
- Add file locking for state management (prevent corruption)
- Fix WebSocket resource leaks and connection cleanup
- Add graceful degradation and circuit breakers

Configuration:
- RedisTTLConfig dataclass with environment variable support
- Template-based docker-compose.yml and nginx.conf generation
- Comprehensive error handling with actionable messages

Documentation:
- AGENT.md: Complete DevOps context for AI assistants
- MULTI_CONTAINER_ARCHITECTURE.md: Technical architecture guide
- Reorganized docs into deploy/docker/docs/
