Just a few minor suggestions for you @jitseniesen.
If a remote call leads to an exception with a `name` attribute (e.g., a ModuleNotFoundError), then add this to the JSON in the reply.

This PR adds support for displaying Polars data frames in Spyder's variable explorer to the Spyder kernels. The type is shown as "Polars DataFrame" and the value as "Column names: xxx" (same as for Pandas data frames). When the user opens an editor, the Polars data frame is converted to a Pandas data frame and sent to Spyder.
This conversion fails if Pandas is not installed in the console environment. To handle this properly on the Spyder side, the last commit extends the error handling in remote calls to also send the
nameattribute (if it exists) of exceptions raised when handling remote calls. This attribute contains the name of the module whose import failed inModuleNotFoundError.This PR is used in Spyder PR spyder-ide/spyder#24558. See there for a video of how it all looks.
