Zone-to-zone clearance knockouts and higher-priority zone subtraction happen after the initial deflate/inflate minimum-width enforcement cycle. These knockouts can carve out material and leave thin copper strips that violate the zone's minimum width constraint. Add a second deflate/inflate pass that runs only when knockouts were actually applied. The result is intersected with the pre-deflate boundary to prevent re-inflation into cleared areas (keepouts, pad clearances, etc.). Fixes https://gitlab.com/kicad/code/kicad/-/issues/23332
