fix vs-version

The Swatinem/rust-cache action was restored before brew installed the
native dependencies. When Homebrew updated glib (2.88.0 → newer) the
cached Rust build artifacts still referenced the old versioned Cellar
path (/opt/homebrew/Cellar/glib/2.88.0/lib), causing a linker failure:

    ld: library 'gio-2.0' not found

Fix by:
1. Moving `brew install` before the rust-cache step so libs are current
   before the cache is consulted.
2. Capturing `brew list --versions glib gtk4 libadwaita` into a
   prefix-key so the cache key changes whenever those packages update,
   forcing a clean Rust build with fresh pkg-config paths.

Linux and Windows cache behaviour is unchanged (MACOS_LIB_VER unset →
empty prefix-key → same default v0- prefix).
