Expand description

Threshold for dictionary size checks in categorical array operations.

Controls when the cmp_dict_in function in kernels/logical.rs switches from dictionary lookups to direct string comparisons. Arrays with fewer unique values than this threshold use optimised dictionary-based comparisons.
