With qualityCutoff=3 (want hi-res), a Soulseek-grabbed CD copy stays below cutoff and
is re-attempted for upgrade. Without a guard, when Qobuz is gated by pacing those
attempts would (a) re-search every owned album each monitor cycle and (b) re-download
a same-quality Soulseek copy that keep-if-better discards — pure churn.
Add an upgrade guard: a >= CD-lossless copy can only be improved by hi-res Qobuz, so
when Qobuz is gated, skip the job WITHOUT searching (pre-search skip); and as a safety
net, skip the download when the best-ranked candidate can't beat the existing copy.
Force jobs always proceed. Extracted the shared keep-existing path into a helper.
