cuML SQL API

Work in progress

The cuML SQL surface is under development. The cuml_* table functions are not yet exposed in a release: there is no cuml Cargo feature yet, and a query that calls a cuml_* function currently fails as an unknown table function. The shape described below is the intended direction and may change.

Algeon plans to expose NVIDIA RAPIDS cuML as SQL table functions over DataFusion SQL sessions, following the same pattern as the cuGraph SQL API and the cuVS SQL API: each cuml_* function reads a relation of feature inputs, runs a GPU machine learning workload, and returns rows you can join and filter alongside the rest of your query.

Until the functions ship, gpu_list_functions does not list a cuml family, and no relation shape or option schema is final.
