Thank you! A few comments so far: could you please update the dev docs to reflect the new flow, instead of updating requirements.txt like we used to (uncommenting # -e ../../)? It would be great to document the new uv flow for local package development. 🙏

@sicoyle as we agreed I've returned the call to os._exit(0) as per this ref:

A call to sys.exit() is translated into an exception so that clean-up handlers (finally clauses of try statements) can be executed, and so that a debugger can execute a script without running the risk of losing control. The os._exit() function can be used if it is absolutely positively necessary to exit immediately (for example, in the child process after a call to os.fork()).

This is a temporary way to handle exit with the grpc instrumentor while we debug and fix properly closing the channels.
The Quickstarts now run to completion 🚀
