While the 'All' listing currently only excludes archived repos, this is a more general solution that, as long as they don't redesign the repository list yet again, should work even with further category display changes.

It also erroneously filters out offsite URLs that contain the root domain, and this isn't fixable without using regex, which isn't always available in the SQLite CLI before version 3.36.0.

HTTP/1.0 does not mandate a Content-Length header in responses since keep-alive connections aren't a thing; the connection closure then signals the end of the response.
This change requires the URL metadata line for processing HTTP/1.0 data, so it plays well with `warc-dump-responses --meta`.
