Expand description

Full eigenvalue decomposition is not implemented in this no-SciRS2 fallback (a numerically stable general eigensolver – e.g. the shifted-QR algorithm with deflation – is well beyond a “naive” reimplementation); honestly report the limitation rather than return a fixed, wrong-sized identity-like result.
