The sign script was re-signing Mach-O executables with --force and
hardened runtime but without --entitlements, stripping entitlements
like allow-jit that Node.js needs for V8. This caused SIGTRAP on
any Mac where the binary went through Gatekeeper validation.
Extract existing entitlements before re-signing and pass them back
via --entitlements so they are preserved.
