feat(colophon): credit u/eriatilox for ideas too

Second name on the list, and the first from somewhere other than a fork —
so the doc comment stops calling this a list of forks, and says what the
`handle` field now carries: it renders verbatim, a bare handle meaning
GitHub and `u/` meaning Reddit, rather than a `platform` field nobody would
keep consistent across two entries.
