Struct RandomProjection 

pub struct RandomProjection { /* private fields */ }

Fit-free projection via random matrix (Johnson-Lindenstrauss).

Generates a fixed 3×n random matrix at construction time. Preserves pairwise distances probabilistically without needing a training corpus. Less accurate than PCA for any specific dataset, but useful when no corpus is available or for quick prototyping.

Deterministic for a given seed.
