[v2.10.1] - 2026-02-18#

Patch release that fixes a critical NEB convergence regression introduced in v2.10.0, where removing the EIGEN_DEFAULT_TO_ROW_MAJOR macro left bare MatrixXd types as column-major, silently corrupting force projections. Also fixes a Python 3.10 compatibility issue and adds a CI-NEB regression test to prevent similar regressions in the future.
