Dev Server doesn't do anything on macOS, M1 Pro, can't be stopped neither

Start by reproducing sf lightning dev app --device-type desktop --target-org jascha/supplierprice --name Customer_Manager on macOS Sequoia with the reported darwin-arm64 and zsh setup. Trace the lightning-dev command entry point and observe file-change handling and Ctrl+C shutdown; done means component changes reach the org and the server exits cleanly.

Summary

When I start the server, the Org pops up correctly, but no changes are reflected, and stopping the server is not possible

Steps To Reproduce:

1. I start the server with sf lightning dev app --device-type desktop --target-org jascha/supplierprice --name Customer_Manager
2. Terminal says Waiting to resolve the Lightning Experience-enabled custom domain...... done
3. Org pops up, with a hint to a running dev server

Expected Result

When I change components, I would expect that it reflects on the org.

Actual Result

Nothing happens. Not even active reloading shows changes. So I guess the changes files aren't pushed to the server?!

Additional Information

Stopping the server isn't working too, I can type CTRL+C but nothing happens, server is stuck.
