/**
 * Packages the release variants from .output into dist/<version>/ and writes
 * dist/release-entry.json recording filename/size/sha256/url for every
 * artifact, plus per-artifact .sha256.txt checksum files.
 *
 * The variant table must stay in sync with `verify:production` (package.json)
 * and scripts/audit-build.mjs — those define the published surface.
 *
 * Usage:
 *   node scripts/package-release.mjs --public-base-url=https://aliyun-oss.yaklang.com/chrome-extension [--dist=dist]
