- Enhanced the SandboxManager to use a sharded locking mechanism for improved concurrency and performance.
- Replaced the global lock with shard-specific locks, allowing for lock-free reads and reducing contention.
- Updated methods for registering, retrieving, unregistering, and counting sandboxes to work with the new sharded structure.
- Improved documentation within the class to clarify the purpose and functionality of the sharding approach.
- Simplified the SandboxLayer initialization by removing unused parameters and consolidating sandbox creation logic.
- Integrated SandboxManager for better lifecycle management of sandboxes during workflow execution.
- Updated error handling to ensure proper initialization and cleanup of sandboxes.
- Enhanced CommandNode to retrieve sandboxes from SandboxManager, improving sandbox availability checks.
- Added unit tests to validate the new sandbox management approach and ensure robust error handling.
