feat(feed): advertise the Yutils feed in knownFeeds

Yutils is packaged for DependencyControl in TypesettingTools/Yutils#2 as
`tstools.Yutils`, which declares the bare `Yutils` name in `provides`.
Advertising its feed here folds it into the officially trusted set, so
ASSFoundation's existing feed-less `Yutils` requirement resolves to it
without ASSFoundation having to reference a 0.4.0 feed that v0.6.x clients
can't parse.

The retired `master` feed is deliberately left untouched, so only v0.7.0+
clients ever discover the feed.
