Description
We could introduce a prepare_jacobian! in addition to prepare_jacobian.
Advantages: we signal that mutation is allowed, which allows us to generate fewer basis vectors (and possibly exploit a sparsity pattern).

Research direction
Start by reviewing the existing prepare_jacobian interface and the in-place operator behavior described in the issue. Determine the API and mutation contract needed for prepare_jacobian!, including how fewer basis vectors or sparsity can be supported; done means the design is agreed and implemented with coverage for the relevant preparation paths.
