Behind a proxy, defer redirect-target DNS to the proxy; without one, keep the resolve-and-pin path. Trust default-registry/CDN hostnames with no local DNS. Fix a nil CancelFunc crash in blobDownload.release.
* transfer: bound stall retries and let the watchdog interrupt them
A download that stalls could never recover. copy derived its own
cancellable context, but the request was built from the parent, so
cancelling on a stall never reached the in-flight body and the read
stayed parked. The stall watchdog could detect a stall it had no way
to stop.
Stall retries were also unbounded: they never incremented attempt, so
the retry loop had no limit, and because backoff was gated on
attempt > 0 they retried with no delay at all.
The request now owns the cancellable context and passes its cancel
down to copy, so a stall aborts the read. Stalls get their own retry
budget before counting against the limit, and backoff is keyed to
every retry rather than only the counted ones.
