fix: add --network-timeout option to yarn install for improved reliability

[prolinkmoon]

Summary

This PR adds the --network-timeout 100000 flag to the yarn install command to improve reliability during dependency installation. This change helps avoid timeout issues in environments with slow or unstable network connections.

Changes Made

• Updated swarm.containerfile to include --network-timeout 100000 in the yarn install command.

Reason

In certain environments (e.g. CI/CD or behind slow proxies), the default timeout for yarn may cause installation to fail. Increasing the timeout ensures a more stable install process.

Notes

• No changes to application logic or runtime behavior.
• Safe, minor change focused on improving developer experience.
