Detailed Description
Type-erased accessor for converting DataVariant to Eigen types.
Provides semantic, easy-to-follow conversion from NDData to Eigen. Companion to EigenInsertion for write operations.
Design principle: All numeric types convert cleanly to Eigen's double representation. Complex types become 2-row matrices (real, imaginary).
