	Analytical gradient of the solvation energy with respect to atomic positions (Hartree/Bohr, 3 × N_atoms).

Detailed Description

No-op solvation model — preserves gas-phase numbers.

Used as the Phase 7A correctness gate and as a sentinel for "solvation off" in code paths that already hold a model pointer.

inlinevirtual

Update from the atomic charges together with the CAMM atomic dipoles (3 × N) and traceless quadrupoles (6 × N, CammMoments::qp layout), so the anisotropic part of the density polarises the continuum too.

The default drops them, which leaves charge-only models unchanged.

Reimplemented from occ::xtb::XtbSolvationModel.
