/**
 * Unified decoration hook — replaces both the old `useShapeDecorations` and
 * `useEdgeLabels` with a single pass per feature.
 *
 * Processing per feature:
 * 1. Collect decorations from `handle.getDecorations`
 * 2. Partition: static anchors vs viewport-aware (`vertex-auto`, `edge-auto`)
 * 3. Resolve static anchors, compute edge properties for `edge-*` anchors
 * 4. `vertex-auto`: `findBestVisibleVertex`
 * 5. `edge-auto`: build `ShapeLabelResolutionContext`, invoke optional
 *    `resolveLabel`, then `computeEdgeAutoPlacement` → placed / hidden
 * 6. Create `kind:"anchor"` marker sources for all placed decorations
 * 7. Build interaction map for Layers to wrap interactive portals
 *
 * Has no dependency on `api.annotations` — consumers that want chrome-bar
 * fallback opt in explicitly via `useMapAnnotation`.
 *
 * @returns Interaction map keyed by source ID.
 * @internal
