rays 245fa79fbf A YouTube feed's spurious 404 or 500 is asked again (#382) ...

YouTube answers some requests for a channel's feed with a 404 or 500
in tens of milliseconds, while the next request for the same feed, or
another channel's 200 ms later, reads. Checked once a day, the 39
YouTube channels in the catalogue missed most days: 178 failures in
the week to 2026-11-04, against 74 in the ten days before, and all 39
read from Tower when asked by hand.

feed::fetch now asks a youtube.com/feeds/videos.xml address again, up
to twice, a second apart, when it answers 404 or 5xx. Other hosts'
404s are real and are not retried. tokio moves from ipx-feed's dev
dependencies to its own, for the sleep; both services build it already.
