… flush test_unit_threedim_loaders: AssetLoader/GltfParser/FbxParser/TinyObj/Ply/Vcg + the PrimitiveCloud parsers, compiled straight into the test (plugin is -fvisibility=hidden). test_unit_primitivecloud: PLY/.splat/.spz parsers + scene helpers. ObjectGallery: explicit llvm profile flush on _Exit + SEGV/ABRT so coverage runs of the render-regression harness still emit .profraw (atop this branch's render-regression mode).

Adds the point-cloud objects: a PLY parser, a .splat binary reader, an SPZ codec (compressed 3D Gaussian splats, via the new spz + zstd submodules), a scene-from-cloud node and a format override, plus the TagAs helper. The asset loader routes .ply/.splat/.spz through them. The existing Splat render node and Splat loader are kept alongside the new family rather than retired, so both remain available.

ObjectGallery --render <name> : add one object, route its texture output to
an offscreen window, play, and exit 0 if it
rendered a full run without crashing (a
render-path crash kills the process, which
the driver attributes to that object).
render-sweep.sh [filter] : run --render for each object on BOTH GL
backends (llvmpipe and the machine's GPU via
X11) and tally crashes.
Texture objects (ISF, images, model display, ...) render clean on both
backends. Two follow-ups: geometry-only objects need a display chain (they
currently abort when run standalone), and the offscreen readback does not yet
composite the routed texture so the non-blank check is informational.

ObjectGallery gains a --shader <file> mode: it loads a shader tester (.fs/.frag/.glsl as an ISF Shader, .cs/.comp/.csf as a Compute Shader) into a process, routes its texture output to an offscreen window and renders it, exiting non-zero if it fails to compile or crashes. csf-sweep.sh drives that over the csf-examples corpus on BOTH GL backends (llvmpipe and the machine's GPU via X11). On the csf-testers set, 100/121 shaders render on both backends; the remaining 21 are geometry-producing compute shaders that need a downstream raster stage to display (see the corpus's tests.txt) — chaining them is the next step. Also fixes the sweep drivers to pass per-backend env via `env`, since bash does not treat VAR=val from an expanded "$@" as assignments.

The PrimitiveCloud point-cloud / Gaussian-splat family — the last piece of the 3D-object work, deferred from #2122 because its build wiring is more involved.
Stacked on #2122; retargets as the stack merges.
What it adds
.splatbinary reader, an SPZ codec for compressed 3D Gaussian splats (via newspz+zstdsubmodules), a scene-from-cloud node, and a format override.TagAshelper, and asset-loader routing for.ply/.splat/.spz.Kept, not retired (per the "keep both" decision)
The upstream 3D branch deletes the old
Splat/render node in favour of this family; here it is preserved — the Splat render node and Splat loader remain registered alongside PrimitiveCloud.Notes
The earlier deferral cited three blockers; two dissolved once built from the branch tip rather than an intermediate commit (the
Gfx::FormatRegistryreference is an empty-stub include at tip, unused), and thelibspz-fPIClink failure was from applying the zstd build wiring incompletely — the complete3rdparty/zstd.cmake+ redirect + spz stub build cleanly.Validation
