Start by reproducing node-gyp rebuild for the reported mmmagic dependency with Node 14.20.0, node-gyp 9.1.0, Python 3.8.10, and Linux. Inspect deps/libmagic/src/file.h and the build output around the missing unistd.h; done means identifying a reproducible project-side fix or documenting that the failure is external to node-gyp.
