# ─── native cross-compile stage ───────────────────────────────────────────────
# Mirrors the go-tools pattern: runs on the build platform (always native amd64

# of under QEMU — turning a 15-hour emulated build into a 30-60 minute one.
# cargo binstall --target fetches prebuilt binaries from GitHub releases;
# for tools without prebuilts it falls back to native cross-compilation.
