resolver: a query cut short by the caller's context records no reason (closes #298)

When the caller's context ends, the next query returns ErrContextCanceled before anything is sent. querySingleType recorded that as a network error, which outranks a timeout, so a nameserver that had only timed out could be reported as "network error: context canceled". It now records no reason for it. Model: opus-5-5

 # Completed Steps

+- 2026-10-15: a query cut short by its caller's context records no reason about
+  the nameserver, so one whose only failures were timeouts is `timeout`, not a
+  network error (closes #298).
 - 2026-10-15: the resolver no longer says its query timeout grows on each try;
  every try waits the same 2 seconds, and the unused `timeoutMultiplier` is gone
  (closes #296).
