🟡 [P2] Preserve the clicked entry across chain normalization

When the setter removes duplicates, as the wWaypoints cycle does, committing can change entry positions as well as IDs. For example, editing 100 to 200 in [-1, 100, 200, 300] and clicking the existing 200 normalizes the chain to [-1, 200, 300]. Reusing index 2 then opens the editor for 300, so subsequent typing modifies the wrong entry. Remap the clicked entry after normalization instead of reusing its previous index.

🟡 [P2] Wait for release on the Main pointer-event pass

An empty-space click with a small, unconsumed mouse movement can now leave search focused. waitForUpOrCancellation internally awaits Final again after checking the requested pass; passing Final makes that second await receive the next event instead. In a down–move–up sequence, the release is checked only for consumption, leaving the detector suspended without calling clearFocus(). Use the default Main pass or a loop that checks every final-pass event.
