Fixed

• dusk:observe lists a merged control once. The walk emitted every node that carries an action, and MergeSemantics keeps each absorbed descendant in the tree as its own node flagged isMergedIntoParent, so an MSSwitch row came back as a 324x44 boundary plus a 44x24 duplicate and an MSButton "Kaydet" as 79x44 plus 79x36, while the platform sees one node. A merged node now yields no candidate and no qN handle; the walk still descends through it, the candidate shape is unchanged, and the boundary is still listed. The candidate count can drop for a screen with merged controls, and a script that held a candidate by position has to re-observe; a dusk:perf_run {role, name, index} target with an index above 0 now counts the same nodes dusk:snap lists. The per-label counter still counts merged nodes, because the find resolver does, so the matchIndex of every surviving handle is unchanged. (lib/src/extensions/ext_observe.dart)
