🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not use the functional updater as a synchronous result.

useTimelineState passes its React setAnnotationRegions setter to useAnnotationRegionCommands. React can defer the updater until after handleAnnotationDuplicate returns. The updater can then assign createdId after the if (!createdId) check. The command returns false, so the duplicate action can show its failure toast while the appended annotation remains unselected.

Keep source lookup and placeSpanAfter based on the current region list. Do not use a stale render-time snapshot. Make useTimelineState maintain a current-regions ref and update it synchronously for every region update. Compute the duplicate and createdId from that ref, then queue a pure state update and select the new annotation.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Do not use the functional updater as a synchronous result.

setZoomRegions and setAudioRegions receive deferred functional updaters. When the source fits, each updater can append the duplicate after the handler returns, while createdId is still null. Both handlers can therefore return false, show the insufficient-space toast, and skip selection. The updater also mutates the ID ref, so replayed execution can advance the ID source more than once.

Make current regions synchronously available from the state owner. Resolve the source, placement, and ID before scheduling. Keep the scheduled updater pure without replacing current-state behavior with a stale render snapshot.
