Changes

• Cap the per-query UDP timeout at min(1.0, timeout) for single-nameserver
  configurations as well as multi-nameserver ones. Previously, when only one
  nameserver was configured (or the system default list had a single entry),
  resolver.timeout and resolver.lifetime were both set to the full
  timeout budget, which collapses dnspython's UDP retry loop to a single
  attempt — a single dropped UDP datagram then consumed the whole lifetime
  and raised LifetimeTimeout, while dig (which defaults to +tries=3)
  would mask the same blip by retrying. dnspython now retries UDP within
  the lifetime window (~2 attempts at the default 2s budget), matching
  dig's behavior in spirit and eliminating spurious single-NS timeouts
  on paths with occasional packet loss.
