Subject: [PATCH] fix: disable duplicate checks when threshold <= 0

If the threshold is `0`, you're basically saying "show me when a package
has 0 or more versions". This will always be true so is a nonsensical
value.

Similarly, `-1` may be set as a way to turn it off but currently does
the opposite (same as `0`).

This change means `-1` and `0` behave as "turn off duplicate checks".
