Yuval Tassa 68537e1e32 Replace mjtSize with size_t for size calculations.
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.

Yuval Tassa 30b903b6c0 Migrate mjModel size fields from int to mjtSize.
This change updates all size-related members within the `mjModel` struct from `int` to `mjtSize`. This allows MuJoCo to handle models with a larger number of elements. Corresponding changes were made to macros, function signatures, and I/O routines to accommodate the new `mjtSize` type.

Alessio Quaglino 9d5063799f Resize keyframes also at the start of compilation.
Previously, it was assumed that attaching was the last operation performed on the mjSpec, so keyframes resulted in the incorrect size. In order to prevent information loss, we now only allow the resize function to expand the keyframe array, since attach should never remove a degree of freedom.

Sam Haves 1fb1810b07 Add ability to specify a material assignment to a mesh asset.
This extends both the spec and the XML definition to allow specification of a material name on a mesh. This material acts as a fallback in the case that the referencing geom element does not specify a material of it's own.
