# Compile + test on every push/PR. The Windows and Linux jobs are the
# compile-feedback loop for the platform-specific code a macOS dev machine
# never builds (`cfg(windows)` transport / process detach / config dir,
# the Linux `/proc` queries, the x11/wayland gpui backends). The macOS job
# guards against regressing the original target.
