build: pin macOS deployment floor at link time (minos) (#13341) 5df57079b5
* build: pin macOS deployment floor at link time (minos)

-mmacosx-version-min was in buildoptions (compile) only, so the linker
stamped LC_BUILD_VERSION.minos from the host SDK — a dylib built on macOS 26
shipped minos 26.0 and today's sonoma build ships 14.0 despite intending 11.0.
Adding the flag to linkoptions makes the floor host-independent (proven: both
sonoma and Xcode-26 builds stamp minos 11.0).
