Summary

Add regression coverage for the executable NanoTabICL guide examples and their model components.

Description of the change

Execute the guide's Python blocks directly to keep tests aligned with the published examples. Cover context and query isolation, permutation behavior, readout shapes, both context-label injection stages, invalid labels, empty queries, and feature-grouping offsets, wraparound, projection, and input dimensions. Parameterize forward checks across float32 and float64 with CPU and CUDA coverage, and initialize attention outputs so behavioral checks exercise attention.
