Description

We have long running tasks and with the current setup it starts a server on :22322 but fails to start if one already exists. This should be handled like vite where :5173 is the default and if one exists there it automatically launches on :5174.

The goal is to not be forced to close the long running ewc session in order to fix a small issue or demonstrate something

Contributor guide

Research direction
Implement automatic port selection: try the default port 22322, and if occupied, increment by 1 until a free port is found. Use Node.js 'net' module to check port availability.
