Three boolean expressions clippy now wants simplified (pipeline's
normalize_wb, engine's learn_as_shot_wb, per nonminimal_bool), a
descriptor_copy only its #[cfg(unix)] test calls (dead on Windows), and
desktop_entries_give_their_program is unix-gated (Path::is_absolute
decides by the platform, and desktop entries run there). None change
behaviour; all four fail cargo xtask ci on this toolchain from main.
