The browser worker image lowers `yield*` only as a whole statement and
rewrites `for await` loops by their source layout, so compressed node-side
entries either fail that lowering or lower to unparseable code. Only the
browser bundles keep compression, which removes about a third of their text.
The bundle-purity assertion now matches the module-loader call regardless of
the quote style compression picks, and the release-pack fixture exercises
the installed package's new documentation requirement.
