Pushing a tag matching v* (or running the workflow manually with an
existing tag) cross-compiles the four supported targets via
`make build-all`, generates a SHA256SUMS file, and publishes a GitHub
release with all binaries attached.
Replace the Python bootstrap script with a Go implementation that
cross-compiles to native binaries for Linux and macOS on x86_64 and
aarch64. The Go port preserves all sections of the original (system
packages, optional Flatpak GUI apps, custom downloads, and the macOS
firecracker VM bridge) and adds first-class pacman support so the tool
works on Arch-family distros alongside Debian, RHEL, and macOS.
A Makefile produces a host binary via `make build` and the full
four-target matrix under dist/ via `make build-all`.
