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++.

- renames the main header file to mjrfilament.h.
- moves filament_util under a "support" folder.

Respect an explicit CMAKE_INTERPROCEDURAL_OPTIMIZATION=OFF
The default-LTO guard checked the value rather than whether it was DEFINED, so an
explicit -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=OFF (used in CI to cut build time)
was silently flipped back ON. Check DEFINED instead; default-on for Release is
preserved when the caller makes no choice.

Speed up CI
~10x faster on the POSIX jobs (~45m -> ~4-5m) and ~2x overall wall-clock.
- Build Studio/Filament and WASM only in their dedicated canary jobs, not in
every matrix job (WASM uses emcc, which ignores the host compiler).
- Compiler matrix -> build_matrix.json with core/extended tiers: PRs build the
core set, pushes to main run the full sweep.
- ccache across build jobs (studio cache keyed on the Filament pin); fix the
Python-bindings build so ccache hits (CCACHE_BASEDIR).
- Disable IPO/LTO on POSIX (it was silently on); keep it on Windows where /GL-off
exposes a latent test bug and build time is not the bottleneck.
- Run ctest in parallel on POSIX (~2x); uv for Python installs (~29s -> ~8s).
- Move MJX (compiler-independent) to a single dedicated job.
- Restrict GITHUB_TOKEN to contents: read; bump actions off deprecated Node20.

Build the gcc jobs with LTO off too
Restores LTO-off for gcc (recovering the build-time win). That surfaces known
gcc-12 -Wrestrict false positives in libstdc++ <char_traits> at -O3; two clean,
behavior-preserving rewrites in the XML writer avoid them. Confirmed gcc-12 and
gcc-14 build clean with LTO off (PR #3325).

Respect explicit IPO=OFF in the Simulate and Sample options too
Apply the same DEFINED check as cmake/MujocoOptions.cmake to the simulate/ and
sample/ subprojects (which carry identical copies of the guard) to keep the three
in sync, as the internal import requires. Since the guard now honors =OFF, stop
forcing IPO=OFF on the tiny samples/simulate CI builds so they keep their default
LTO and don't expose the gcc -Werror false positives that -O3-without-LTO triggers.

When an mjpResourceProvider's open callback returns 0 (failure), MuJoCo does
not invoke the corresponding close callback. Previously, several resource
provider implementations allocated heap memory or system file handles before
encountering an error, failing to clean them up before returning 0. This change addresses these leaks across the codebase and clarifies the API contract.

Use the jump flood algorithm to render an outline around selected
objects. This requires using custom post-processing shaders and
render passes which is managed by a new "Outliner" class.

Instead, use materials to determine the layer mask of an object.
This hides the details/complexities of how layers are used
to render different passes from the user and will allow the
renderer to do more advanced rendering passes.

The sensor engine now correctly retrieves body IDs for contacts involving Flex elements by using mj_flexBody when a geom ID is -1. This allows contact sensors to detect and report forces/torques on bodies involved in Flex contacts.

The obj_decoder plugin is updated to parse line segments ('l') from OBJ files and represent them as degenerate triangles. The user_flexcomp compiler now supports flex dimensions of 1, using these parsed line segments to define the 1D flex elements. The compile sample's error reporting is also improved.
