#   build/floatplane_<ver>.zip        plugin package                   -> release asset
#   build/floatplane_<ver>.zip.md5    checksum

# Usage: scripts/package.sh [version] [base-url-for-zip]
#   version   defaults to the version in build.yaml; CI passes X.Y.Z.N
#   base-url  URL prefix where the zip will be downloadable (for manifest.json sourceUrl)
