We can only use the MjSpec wrapper, not the raw::MjSpec struct in the API.

This clarifies the difference between attaching a full spec, which converts the worldbody to a frame, and attaching a specific body (or frame).

When specified, child asset with repeated names will override parent's, rather than throw an error. Default behavior is to override.

Old API:
```
site.attach(child_spec)
frame.attach(child_spec)
```
New API:
```
parent_spec.attach(child_spec, frame=frame_name_or_object)
parent_spec.attach(site_spec, site=site_name_or_object)
```
This enables accessing the parent object during attach, which will be used in a follow-up CL to automatically append the child assets to the parent.

This enables associating assets with a spec object.
Also, remove `spec.compile(assets)` and replace it with the `spec.assets` attribute, which must be be set before compile if assets are present.

Replace .attach() with .attach_body() where a body is passed as a first argument instead of a spec that is expected by .attach().
+Fix typo.

- `qLDiagSqrtInv` is only required for the dual solvers. It is now computed as-needed rather than unconditionally.
- `mj_solveM2` now requires a new input array `sqrtInvD` which contains the square root of the inverse diagonal D (formerly saved in `qLDiagSqrtInv`).

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.

This method allows users to bind a spec to a model or data object, making it less verbose to access its arrays.

Using ids is error prone in scenarios of repeated attachment and detachment. Python users are encouraged to use names for unique identification of model elements.
