Description
Currently, if we:
- Start the reticulate session
- Shutdown the R session
- Get an error message with:
Connection to server got closed. Server will not be restarted.
This happens because ending the R process will endupt shutting down child IPykernel which in turn is running the LSP server. When that connection is interrupted, the LSP client raises the message we see.

Research direction
Reproduce the sequence of starting reticulate, shutting down the R session, and observing the child IPykernel and LSP connection. Trace the shutdown path across the R session, reticulate session, IPykernel, and LSP client to identify where orderly cleanup belongs. Done means shutting down R also stops the related sessions without the connection-closed error.
