Port 7335 (ringpop) is already commonly used by Figma

I don't think this is really a "bug" but a common issue for me nonetheless. When trying to start temporalite it fails for me with the following error message:

The terminal process "/Users/schickling/.nix-profile/bin/fish '-c', 'temporalite start --filename tmp/temporalite.db --namespace default'" terminated with exit code: 1.

This seems to be due to a port conflict on 7335 between Temporal via ringpop and figma_agent.

My current work around is to run killall figma_agent

Update: After learning more about ringpop it doesn't seem to be needed by temporalite and thus should not expose this port.

Thanks!
