Places a copy immediately after the selection via settings actions or Ctrl+Shift+D (fixes webadderallorg#382).

Suggested reviewers: Merge Risk: 🟡 Moderate · up to Near the timeline end, duplicated regions can lose duration instead of reporting insufficient space. Duplicate actions can also report failure while adding an unselected copy, and annotation settings lack the requested Duplicate button. These user-visible feature failures should be fixed before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

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.

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.

Reject partial duplicates. A duplicate must retain the source duration. Truncating it at the timeline end violates the size-preservation requirement and prevents the insufficient-space failure path.

Description
Adds a Duplicate action for selected timeline zooms, annotations, and audio regions. The copy is placed immediately after the original so users can keep the same look/settings and only adjust timing or content.
Also adds Ctrl+Shift+D (configurable) when the timeline is focused, and Duplicate buttons in the settings panel next to Delete.
Motivation
Issue #382 asks for a way to duplicate anything on the timeline — e.g. reuse an annotation style, zoom size/location, or the same sound — without recreating it from scratch.
