wallpaper.rs/pywal.rs/theme.rs each shelled out via a bare
Command::new(...).status() with no timeout — a wedged awww-daemon, pywal
choking on a corrupt/huge image, or a hung bread-theme reload could each
block breadpaper indefinitely. Switched to bread_utils::proc::run (path
dependency for now, see the TODO in Cargo.toml), matching the exact
"anything shelling out to awww" case named in tonight's ecosystem-utils
audit.
CLI tool that sets a wallpaper with awww, generates a pywal colour
palette, and reloads bread-theme to recolour all running bread GTK apps.
Includes CI workflows, bakery metadata, and Arch PKGBUILD.
