Adding the SIGTERM handler had introduced the cfg(unix) dependency
section above five cross-platform dependencies, silently making zip,
memmap2, glam, dirs, and skia-safe unix-only — invisible on mac/linux
gates, fatal on the windows runner. Only libc belongs in that section.
The complex-script test file's shared imports and constant now carry
the same macOS gate as every test in it, so linux clippy stops flagging
them as dead.
