Add a build-linux-arm64 job (native arm64 runner, same Dockerfile so the glibc target matches the x86_64 build) that produces libpitaya-linux.so for aarch64, and include it in the package: package.sh copies it to PitayaNativeLibraries/Linux/arm64/, with a plugin meta targeting Standalone Linux64 / CPU ARM64. Purely additive — the existing x86_64 lib and its meta (Linux64 CPU x86_64) are unchanged, so x86_64 builds are unaffected and Unity selects the right lib per build architecture. Enables Unity dedicated servers / game rooms to run on Linux arm64 (Graviton). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Adds Linux arm64 (aarch64) to the build/release pipeline so
com.wildlifestudios.nuget.libpitayaships an arm64 native lib — enabling Unity dedicated servers / game rooms to run on Linux arm64 (Graviton) hosts.Changes (purely additive)
.github/workflows/build-and-release.yaml: newbuild-linux-arm64job (runs onubuntu-24.04-arm, uses the sameDockerfileso the target glibc matches the x86_64 build), uploadinglibpitaya_linux_arm64. Added to thepackagejobneeds.package.sh: copies the arm64 artifact intoPitayaNativeLibraries/Linux/arm64/.package/PitayaNativeLibraries/Linux/arm64/libpitaya-linux.so.meta(new): plugin meta targeting Standalone Linux64 / CPU ARM64, plus the folder.meta.x86_64) are unchanged → x86_64 builds are unaffected; Unity 6 selects the right lib per build architecture (confirmed the importer acceptsCPU=ARM64for Standalone Linux64).Validation
An arm64
libpitaya-linux.sobuilt this way (native aarch64, glibc-matched) was verified withdlopen+LD_BIND_NOWinside the target arm64 game image — loads with all symbols resolved. NEEDED:libz.so.1, libm, libc(OpenSSL linked statically), a subset of the x86_64 lib.Note
Same
DllImportname in a separateLinux/arm64/folder (mirrors the existing Android arm64/armv7 layout) so only one lib is active per build arch.
