/**
 * Fills the version and sha256 values of the packaging files (docs/packaging/homebrew-tap/Formula/qqq.rb for Homebrew,
 * docs/packaging/qqq.json for Scoop) from packages/cli/package.json and a release's SHA256SUMS.
 * Run it on the binaries that were uploaded to the GitHub release, not on a local rebuild: the
 * commit is stamped into each binary, so every build has different checksums.
 *
 * Refuses to write anything (exit 1, both files untouched) when a sum is missing, is not 64 lowercase hex digits,
 * is all zeros, or when a placeholder in the files is left unfilled.
 *
 * Usage: node scripts/update-packaging.mjs [dist/SHA256SUMS]
