bun run start-bin not working local setup

[Siafu]

Following the local setup guide
https://github.com/CodebuffAI/codebuff/blob/main/CONTRIBUTING.md

Step running bun run start-bin just hangs with output:

codebuff/npm-app > 
Could not connect. Retrying...

Troubleshooting:
Confirmed its not a network or firewall issue.
I am able to run wscat -c ws://localhost:4242/ws successfully.
