CMake adds the imported mujoco target's include dir as -isystem, so with
system_headers sloppiness ccache stopped hashing the public MuJoCo headers.
A header-only change (new mjData field, new enum value) then went undetected
and ccache reused objects compiled against the old struct layout, yielding an
ABI-mismatched binding: wrong field offsets (garbage in struct/pickle tests),
stale mjENABLESTRING/mjNENABLE, and mjSpec-vs-mjData signature mismatches.
Removing system_headers makes ccache hash these headers and recompile on
change. The mtime/ctime flags stay (they absorb pip's per-run temp-dir churn
without affecting content detection).
Compiler warnings are now accumulated in a vector of strings within the mjSpec object. New API functions `mjs_numWarnings` and `mjs_getWarning` are added to access these warnings. The compiler's log handler now chains warnings to the global log handler, ensuring they are still displayed immediately. Call sites in `mj_loadXML`, `mj_compile`, and the Python and WASM bindings have been updated to use the new warning API.

Use box midpoint to choose finite-difference direction in jacobian_fd
When bounds are provided, `jacobian_fd` chooses each coordinate's
finite-difference direction so the perturbation steps away from the nearer
bound. It compared `x` against `0.5 * (bounds[1] - bounds[0])`, which is half
the box *width*, not the box midpoint. For bounds that are not centered on the
origin this selects the wrong direction, and at the lower bound the perturbation
steps outside the box.
Compare against the midpoint `0.5 * (bounds[0] + bounds[1])` instead. Adds a
regression test checking that all residual evaluations stay within an off-center
box when `x` is at the lower bound; it fails before this change and passes after.

Expand jacobian_fd bounds test and avoid midpoint overflow
Use the distributive form `0.5*lo + 0.5*hi` instead of
`0.5*(lo+hi)` to avoid overflow for extreme bound values.
Expand the single-case test into a parameterized subTest covering
all four boundary positions (lower/upper of positive and negative
off-center boxes), and rename it to `test_jacobian_fd_respects_bounds`.

Switch MJX DataJAX to use the CSR-format `M` as its primary sparse inertia representation, matching MuJoCo C `mjData.M`. This allows both `mjData.qM` and `mjModel.mapM2M` to be deleted in the future.

- Move SimToView and ViewToSim dataclasses from async.py to viewer_protocol.py (adding a user_data field) to consolidate IPC protocol definitions.
- Remove the simulated Network class and latency UI controls from async.py to simplify the example and focus on core multiprocessing communication.
- Use parser.parse() in main() for cleaner and more direct MuJoCo model loading.
- Add cancel_join_thread() to multiprocessing queues and a join timeout to prevent atexit handlers from blocking during process shutdown.

This change adds py::gil_scoped_release to various functions in the parser, renderer, sim and ux modules of the MuJoCo Studio Python bindings. This allows other Python threads to execute while these C++ functions, which can sometimes be time-consuming, are running. The two heaviest operations Present() (rendering) and Advance() (physics) now both release the GIL in C++.
