dev-python/xgrammar: Keyword 0.2.6 for ~arm64

Matches 0.2.5, which already carries it. 0.2.6 differs from 0.2.5 only in
the dropped upstream transformers cap and the retired align-tests backport,
neither of which is arch-specific.

dev-python/xgrammar: gate Triton on the arch, not on CUDA

Upstream's marker is platform_machine == 'x86_64', and the auto backend
picks the Triton kernel for any tensor whose device.type is "cuda" --
which ROCm tensors also report. Requiring Triton only under the cuda flag
would therefore leave an AMD host raising ImportError at first GPU use,
and dev-python/vllm's rocm target pins ~dev-python/xgrammar-0.2.2 exactly.

virtual/triton is ~amd64 only, so the arch gate keeps the dependency off
arm64 just as a cuda gate would.

dev-python/xgrammar: remove orphaned 0.1.33 patch

No ebuild has referenced it since the 0.1.x line was dropped; the three
surviving versions apply the toolchain-flags, load-binding and
cuda-host-compiler patches only.

dev-python/xgrammar: drop 0.2.3

Last two are 0.2.5 and 0.2.6; 0.2.2 stays because dev-python/vllm pins it
exactly. Both patches 0.2.3 referenced are shared with the survivors, so
files/ is untouched.

dev-python/xgrammar: add 0.2.6

The align-tests backport is obsolete: it carried upstream commit 40aa80ba,
which is an ancestor of v0.2.6, so it no longer applies and is dropped from
PATCHES. The other three still apply and the pinned dlpack submodule commit
is unchanged.

Upstream also removed its transformers <5 cap and explains why in the
pyproject, so the atom follows; keeping the cap would have held xgrammar to
4.57.6 even though the tree ships 5.16.1.

dev-python/xgrammar: document gcc:15 JIT coupling on 0.2.3 and 0.2.5

The cuda? sys-devel/gcc:15 runtime dep and the bundled
cuda-host-compiler patch are coupled: the CUDA token-bitmask kernel is
JIT-compiled at import via torch.utils.cpp_extension, and the patch
hardcodes the /usr/bin/gcc-15 fallback that a CUDA bump must raise in
lockstep with this slot. cuda_gccdir cannot resolve it because JIT runs
on the user's machine at import, not at build time. 0.2.2 already
carried this note; add it to 0.2.3 and 0.2.5 so the coupling is not
silently lost on the newer ebuilds.

dev-python/xgrammar: document the gcc-slot coupling to the cuda host-compiler patch

The cuda? sys-devel/gcc:15 runtime slot and the /usr/bin/gcc-15 fallback in the cuda-
host-compiler patch must move together, but nothing said so, so a future CUDA bump
could raise the slot and leave the patch pointing at a gcc the new nvcc rejects.
Spell out the coupling and why cuda_gccdir cannot replace the fallback (the kernel
JIT-compiles on the user's machine at import, where the eclass helper is
unavailable).

dev-python/xgrammar: fix CUDA 13 runtime JIT

The CUDA bitmask backend JIT-compiles through PyTorch and otherwise inherits an

with the supported GCC slot as the default.

dev-python/xgrammar: add 0.2.5

Upstream stopped publishing PyPI sdists at 0.2.4 (0.2.4 and 0.2.5 are
wheels-only), so switch SRC_URI from pypi_sdist_url to the GitHub release
tag and stage the dlpack git submodule (headers on XGRAMMAR_INCLUDE_PATH,
installed by the top-level CMakeLists) separately, since GitHub's archive
omits submodule contents. googletest and cpptrace stay unbuilt with our
options (XGRAMMAR_BUILD_CXX_TESTS / XGRAMMAR_ENABLE_CPPTRACE default OFF)
and picojson is vendored in-tree, so only dlpack needs staging.

Also add the transformers<5 cap the 0.2.5 pyproject declares (v5 breaks
tokenizer loading in TokenizerInfo.from_huggingface); 0.2.3 predated it.

also probes accelerator device nodes; addpredict /dev/kfd and /dev/accel
in python_compile so the sandboxed build does not abort.

dev-python/xgrammar: symlink bindings into tvm_ffi/lib

xgrammar/load_binding.py calls tvm_ffi's load_lib_module() without
passing extra_lib_paths, so tvm_ffi searches only its own lib/ dirs
and a few PATH entries — none of which include xgrammar's
site-packages dir where the .so lives. Any consumer (e.g. vllm)
dies at xgrammar module init with "Cannot find library
libxgrammar_bindings.so".

Upstream's wheel apparently works by accident — tvm_ffi's wheel
layout differs from a normal site-packages install. Add a
python_install_all hook that creates a symlink at
${tvm_ffi}/lib/libxgrammar_bindings.so pointing at xgrammar's own
.so. Symlink is owned by this package's CONTENTS.

Workaround, not proper fix. Upstream-able fix is patching
xgrammar's load_binding.py to pass extra_lib_paths=[Path(__file__).
parent]. Switch when there's appetite for a maintained patch.

dev-python/xgrammar: add 0.2.0

Upstream's `0.1.34+` line gained a hard dep on apache-tvm-ffi (TVM's
FFI shim). The previous 0.1.33 ebuild's stay-pin comment is now
obsolete: apache-tvm-ffi-0.1.11 lands in this overlay, so 0.2.0
solves on the consumer side (vllm pins >=0.1.32, <1.0.0; 0.2.0 fits).

Build-check skipped: xgrammar's CMake configure does
find_package(tvm_ffi) which requires apache-tvm-ffi already merged on
the host (its wheel installs the cmake config at
/usr/lib/python*/site-packages/tvm_ffi/share/cmake/tvm_ffi/). pkgcheck
passes; trust upstream metadata pending end-to-end pre-push validation.

Upstream also lists `triton` as a runtime dep on Linux x86_64, but
neither this overlay nor ::gentoo packages dev-python/triton, and the
xgrammar grammar-matching paths vllm exercises don't require it. Note
left inline; revisit if/when triton is packaged.

dev-python/xgrammar: new package

MLC's structured-generation engine for LLMs (CMake/scikit-build-core
+ nanobind C++ extension). Required by dev-python/vllm at
>=0.1.32, <1.0.0.

Pinned to 0.1.33 because 0.1.34+ added a hard runtime dep on
apache-tvm-ffi which isn't packaged. nanobind pin (==2.5.0 upstream)
relaxed to >=2.5.0; built clean against ::gentoo's 2.12.0.

NonsolvableDepsInStable is policy noise — pytorch and transformers are
~amd64 only too.
