CI's pinned LLVM ships ld.lld, and the compiler links Linux executables
with it whenever clang finds it. The Sandbox image and the managed-image
bootstrap installed clang-22 without lld-22, so Sandbox builds linked
with GNU ld: static hello came out at 99 KB instead of 65 KB, and
runtime-tree-shaking failed only in Sandboxes. Install lld-22 in both
and check that clang finds it.

LLVM 22 CMake exports reference the Polly libraries, so building the LLVM helper in a sandbox started from vercel/sandbox/universal fails without libpolly-22-dev. Custom images that already contain it are unaffected.
- Pin GNU runtime packs to glibc 2.36 Zig targets and reject incompatible imports.
- Provision verified Zig builds and exercise published artifacts on Debian Bookworm.

Build the Linux LLVM helper and runtime pack before running both test lanes, and align native cache contracts with the current target policy. Full managed Sandbox gate passed.
