The parsing added in https://github.com/unjs/nitro/pull/1753 could be reused here (and should be extracted to cookie-es for that purpose, i.e. https://github.com/unjs/cookie-es/issues/17).

Upcoming h3 v2 will be based on web apis with event.request.headers.getSetCookie() / event.response.headers.getSetCookie()

Properly parsing Set-Cookie can be done with parseSetCookie in latest cookie-es package.
