Timeline moves and resizes previously snapped only to the beat grid; they now also snap the dragged edge to other clips' start/end, the playhead, and the composition bounds, whichever is nearest within the existing threshold. Beats fold in as one target kind, so beat snapping is unchanged. Snap logic lives in a new pure timelineSnapTargets module with unit tests; a snapped edge shows a guide line (beat highlight, else a thin accent line) for both drag and resize.
