Greptile Summary

Adds comprehensive Docker Swarm support including services, stacks, nodes, tasks, configs, and secrets management.

Key Changes:

• Added complete swarm service backend with CRUD operations, pagination, and log streaming
• Implemented stack deployment engine using Docker Compose specifications
• Created WebSocket endpoint for real-time service log streaming
• Built full frontend UI with service editor, stack deployment, and cluster management
• Added proper error types and validation across the stack

Code Quality Concerns:

• Widespread naming convention violations: numerous unexported Go functions missing required "Internal" suffix per project coding standards (affects swarm_service.go, stack_deploy_engine.go, log_stream_util.go)
• The naming violations should be addressed to maintain consistency with project conventions

Positive Aspects:

• Comprehensive feature implementation with proper error handling
• Well-structured type definitions with good documentation
• Frontend code follows Svelte 5 best practices
• Basic test coverage for UI components

Confidence Score: 3/5

• This PR is safe to merge with code style improvements needed
• Score reflects widespread naming convention violations in Go code (unexported functions missing "Internal" suffix), but no critical bugs or security issues found. The implementation is solid with proper error handling, type safety, and test coverage.
• Pay attention to backend/internal/services/swarm_service.go, backend/pkg/libarcane/swarm/stack_deploy_engine.go, and backend/internal/services/log_stream_util.go for naming convention fixes
