Subject: [PATCH 1/3] chore(build): Replace es-check with an acorn-based script

es-check only ever ran acorn.parse() on our build output, which a small script
does too. The old per-package globs (`build/esm/*.js`) were not recursive and
only covered ~560 of ~3100 built files; the script checks all of `build/`.

Subject: [PATCH 3/3] chore(remix): Check the Remix 3 client bundle against
 ES2022

web-vitals 6 is inlined untranspiled. Its Array.prototype.at use is guarded
since #26347, and its remaining ES2022 syntax (public instance class fields)
runs on all supported browsers.
