The gtklock module is Wayland-only and its GNU ld link flags
(--whole-archive) do not exist on macOS, so the macOS build stopped
there. macOS now builds just the PAM hook and the display binary, which
is all the Homebrew formula installs; libdl is optional (it is part of
libSystem on macOS).

Cargo names a cdylib .dylib on macOS, so copying libahfail_pam.so out of
the target directory failed there, as the first real macOS build in the
Homebrew tap's Actions showed. The installed name stays .so.

ahfail locks the screen itself instead of hooking another locker: Wayland
through ext-session-lock-v1 (gtk-session-lock), X11 through an input grab.
It authenticates against its own PAM service, /etc/pam.d/ahfail, so a
package never has to edit another package's PAM file.
One command for every platform: ahfail (lock), ahfail test (the effect
without locking) and ahfail doctor (what is missing, with the fix).
Enter is handled directly and the entry uses no input method, since the
Wayland text-input IM swallowed Return. Sprites avoid the password box
in window coordinates, and placement gets 100 tries instead of 10.
