Re-architect the timeline row model from data-track-index rows to stacking layers. Rows represent stacking layers per context: explicit-z clips merge onto one track when they share a z and don't overlap in time; auto-z clips stay one row each (DOM order); audio is pulled into its own bottom lanes. Rows keyed by a stable layer id, not data-track-index. Vertical drag always writes z-index, never track: drop onto a layer joins it (same z), between layers interpolates a new z, past the ends creates a new front/back layer. data-track-index is never rewritten; #958 holds. Adds hasExplicitZIndex capture (computed z != auto). L1: hasExplicitZIndex on the element model L2: buildStackingTimelineLayers (layer-based rows) L3: layer-aware vertical drag (join / interpolate / new-extreme)
