Building rapidsnark from source in build.rs required cmake/nasm/gmp on every runner, which the self-hosted CI hosts lack. Instead, host pre-built -fPIC static archives as a fork GitHub release and download them like before. - build.rs: reverted to the download-based approach (the PIC archives are built on glibc 2.35 so they carry no __isoc23 references; no compat shim needed). - download_rapidsnark.sh: Linux x86_64/arm64 now download the -fPIC rebuilds from this fork's `rapidsnark-pic-*` release; macOS/iOS/Android keep using the upstream iden3 archives (which work fine). - Add .github/workflows/build-pic-archives.yml: builds the -fPIC archives (rapidsnark + GMP) inside a glibc-2.35 container and publishes/updates the release. Trigger by pushing a `rapidsnark-pic-*` tag or via workflow_dispatch. Verified locally (glibc-2.35 container): the produced archives link into a -shared cdylib with rust-lld.
