fix: match FormatJS Linux N-API release wiring

[longlho]

Summary

• match FormatJS by routing Linux N-API release targets through GNU release wrappers instead of musl cdylib targets
• align rules_rs/llvm pins with FormatJS so Linux .node artifacts do not depend on libc++.so.1, libc++abi.so.1, or libunwind.so.1
• keep Linux package artifacts to the .node payload and smoke-test for unresolved shared libraries

Verification

• bazel test //...
• bazel build --compilation_mode=opt //crates/codescythe_cli:release_binaries //crates/codescythe_napi:release_nodes //packages/codescythe:package //packages/codescythe-darwin-arm64:package //packages/codescythe-linux-amd64:package //packages/codescythe-linux-arm64:package
• objdump -p on linux-amd64/linux-arm64 .node outputs: no NEEDED entries for libc++.so.1, libc++abi.so.1, or libunwind.so.1
