slang-bin: add version 2026.18

Binary repack of upstream's official Linux x86_64 release tarball.
Building slang from source pulls in LLVM plus several bundled
dependencies, so the prebuilt tarball is packaged instead.

The tree is installed under /opt/slang-bin-$VERSION with the command
line tools symlinked into /usr/bin. The binaries resolve their libraries
through a RUNPATH of $ORIGIN/../lib, which follows through the symlink,
so no wrapper is needed.

kitty 0.49.0 and later require slangc at build time to compile their
shaders, which is the reason this package exists.

+Slang is a shading language and compiler maintained by the Khronos
+Group. It extends HLSL with modules, generics, interfaces and automatic
+differentiation, and targets SPIR-V, GLSL, HLSL, Metal, WGSL, CUDA and
+C++.
+
+This is a binary repack of upstream's official Linux x86_64 release
+tarball, not a source build. Building slang from source pulls in LLVM
+along with several bundled dependencies, so the prebuilt tarball is
+packaged instead.
+
+The tree is installed under /opt/slang-bin-$VERSION and the command line
+tools (slangc, slangd, slangi, slang) are symlinked into /usr/bin. The
+binaries locate their libraries through a RUNPATH of $ORIGIN/../lib, so
+the bin/ and lib/ directories must stay siblings; do not move them
+apart.
+
+This package is x86_64 only. Upstream also ships an aarch64 tarball,
+which this script does not handle.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+slang-bin:
+slang-bin: Slang is a shading language and compiler from the Khronos Group.
+slang-bin: It extends HLSL with modules, generics and interfaces, and compiles
+slang-bin: to SPIR-V, GLSL, HLSL, Metal, CUDA and C++.
+slang-bin:
+slang-bin: This package provides the slangc command line compiler, the slangd
+slang-bin: language server, and the slang runtime libraries.  It is a binary
+slang-bin: repack of upstream's official Linux tarball and is x86_64 only.
