CovTools 0.5.7

• Replaced the external generalized-eigenvalue dependency with internal symmetric-definite matrix-pair helpers based on a Cholesky reduction.
• Removed an obsolete native generalized-eigenvalue wrapper.
• Corrected positive-definite hard-threshold selection and now verify every returned covariance estimate against the documented eigenvalue tolerance.
• Corrected Power-Euclidean distances and means for negative powers, fixed Procrustes size-and-shape distances, and covered scalar and one-slice inputs.
• Corrected bandwidth selection and matrix construction in the Banerjee, An, and Lee banded precision estimators.
• Corrected graphical-lasso BIC scoring and return the sparse positive-definite ADMM estimate.
• Centered covariance diagonality tests, restored the documented Cai test result field, and added minimum-sample and degenerate-data checks.
• Sequential cross-validation and BIC selection no longer create socket workers; parallel paths now clean up workers without changing the caller’s global foreach backend.
