Set the default event bus port to 0 to avoid conflicts

[paperclover]

this issue is closed without a real solution: #198. just told to not run more than one of them by disabling, or manually set a different port per project. this solution is bad because it means i cant run different apps, especially if im cloning someone else's codebase, and having both of them chill.

instead of hardcoding 42069 just set it to 0, the actual port doesn't matter and can be random since you don't directly connect to it in your browser.

This has been solved internally already, you're probably running an older version of devtools-vite if you're hitting issues. It now starts automatically on a free port and wires everything up
