Description
Currently two string columns can be "horizontally" concatenated (i.e. element-wise). There is not a libcudf concatenate that takes a single scalar prefix and a string column. However it seems that replace_slice could be used to implement such. If this is added, the hypergraph implementation can then be improved to use categoricals by default, to mitigate the risk of running in to global string column limits.

Research direction
Start at the libcudf replace_slice entry point mentioned in the issue and trace how string-column concatenation is exposed in this Node project. Inspect the hypergraph implementation to understand the downstream use case; done means supporting a scalar prefix with a string column and enabling that implementation to use it.
