Add a new mjpEncoder plugin type mirroring the existing mjpDecoder pattern.
Encoders serialize an mjSpec + mjModel to an mjResource for a given format.
New API functions:
- mjp_registerEncoder: globally register an encoder
- mjp_defaultEncoder: zero-initialize an encoder struct
- mjp_findEncoder: look up an encoder by filename extension or content type
The mjfEncode callback takes (mjSpec*, mjModel*, mjVFS*, mjResource*) and
returns 0 on success. Writing to mjResource keeps symmetry with the decoder
reading from mjResource and leaves the door open for writable resource providers.

The `vertcollide` attribute in flex and flexcomp contact specifications has been removed since the next mjWarp release will support flex collisions. This attribute was previously used to enable vertex-based collisions by adding sphere geoms at flex vertices. The functionality associated with this attribute has been deprecated and removed from the XML parser, documentation, and internal data structures. Affected example XML files have also been updated.

This CL replaces the header-parsing autowrap system for generating
MuJoCo C# bindings (MjBindings.cs) with a new generator that uses
the mujoco.introspect module. The new generator reads pre-parsed
API data from introspect's enums, functions, and structs modules
instead of parsing C headers directly.
Changes:
- New: generate_cs_bindings.py in third_party/py/mujoco/codegen/
- Updated: genrule in unity/mujoco/BUILD to use codegen
- Updated: MjBindings.cs regenerated from codegen
- Removed: entire autowrap/ directory (9 files)
- Removed: transitional validate_codegen.py
The validate test continues to verify that the genrule output
matches the checked-in MjBindings.cs.

mjrRect is a common type that will be re-used across different
rendering APIs, not just mjr_ APIs.

The pybind for recompile was not releasing the GIL when it called mj_recompile, this can caused deadlocks with the
asset loading threads. For example if a resource provider was trying to call Python.
To resolve this the GIL is release just for the mj_recompile.
Addresses: https://github.com/google-deepmind/mujoco/issues/3118
The next release will include breaking changes, so this bumps the major
version to reflect that.

Hiding the dock icon after the viewer window closes triggers an
asynchronous screen/dock reconfiguration via SkyLight. Without
draining the main run loop, the resulting NSScreen invalidation
notification is dispatched to a GCD worker thread, which hits
NSScreen's main-thread assertion and crashes the process.
Drain the main NSRunLoop briefly after setActivationPolicy: so the
reconfiguration is processed on the main thread.
WaitForAtomicNoGil spins until the render loop consumes a pending
set_texts/set_figures/set_images request (atomic == expected). If the
user closes the viewer window after a request is submitted but before
the render loop consumes it, the render loop exits and the atomic is
never updated. The calling thread spins forever, preventing the
process from terminating.
Check exitrequest inside the spin loop so the wait bails out once the
viewer is shutting down.
- Detect linker type (lld-link vs ld) and use the appropriate stack flag: /STACK:16777216 for lld-link, --stack,16777216 for MinGW ld
- Filter out stack-related flags from Python binding modules to prevent crashes when loading MuJoCo as a DLL in Python
Fixes#3011
* Replace various MJOPTION_ macros with a single MJOPTION_FIELDS.
* Use XVEC macro to denote vector members where there is a mixture of
vector and scalar members in a given struct type.
* Split up MJVISUAL_FIELDS into separate macros for each substruct.
* Modify engine_print.c and Python bindings struct.h/cc to use the
new X macros.

This is to properly handle the case where the interpreter wants to exit immediately, e.g. when `mjpython --version` is run.
Currently, we call `PyGILState_Ensure` regardless of the result of `Py_InitializeFromConfig` resulting in a segfault, as in issue #2870.
