# Build and test on every push / PR. `release.yml` only ever fires on a tag, so
# without this nothing compiles the Linux target until release time — and the
# Linux-gated code (audio/pulse.rs, the non-Windows half of keys.rs,
# autostart.rs) is invisible to a Windows developer's compiler entirely.
