Add mju_mat2Rot.
...
This function extracts the 3D rotation from an arbitrary 3x3 matrix by refining the input quaternion. It is based on the paper "A robust method to extract the rotational part of deformations" by Müller, Matthias, Jan Bender, Nuttapong Chentanez, and Miles Macklin.

Replace flex_xvert0 with flex_vert0
...
`flex_xvert0` stored the Cartesian position of the vertices in `qpos0`. This array was unused, so it is now replaced with `flex_vert0`, which still contains the positions of the vertices, but normalized on the bounding box of the flex so that the coordinates are in `[0,1]^m->flex_dim`. This will be useful in the future for using different interpolation methods for computing flex deformations.

Avoid changing semantics of mjsPlugin.name across XML sections.

The `extension` section used to discard the plugin name and write the instance name in `plugin.name`, while all of the other sections wrote the instance name in `plugin.instance_name` and optionally the plugin name in `plugin.name` (via the function `OnePlugin`). Now all plugin names are in `plugin.plugin_name` and the instance is written in `plugin.name`, so that it is possible to lookup a plugin via its unique instance name.
