Refactor flex stiffness storage to support variable sizes.
...
This change introduces `nflexstiffness` and `flex_stiffnessadr` to allow flex stiffness matrices to have sizes other than the fixed 21 per element. Higher-order flexes can now store larger stiffness matrices based on their number of nodes. The `flex_stiffnessadr` array provides the starting index for each flex's stiffness data within the `flex_stiffness` array.

713b5524bc
Introduces a new "strain" equality mode (flex_edgeequality = 3) for flexcomps with trilinear interpolation. This mode enforces constraints on the three invariants of the Green-Lagrange strain tensor at 8 Gauss quadrature points within each flex element, resulting in 24 equality constraints per flexcomp.
...
Also fixes a bug when attaching a flex with constraints.

Replace mjtSize with size_t for size calculations in engine.

Use unsigned size_t instead of signed mjtSize for size multiplications to avoid Clang's overflow-checking intrinsic. This is semantically correct as size calculations are inherently unsigned.
