scripts: add 7za shim that swallows benign dylib symlink errors

Wrap 7za so a "Cannot create symbolic link" failure on libcrypto/libssl .dylib entries exits 0 instead of failing the extraction; all other non-zero exits pass through. Also picks up npm lockfile normalization. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
