v0.3.2 — JSON region bounds rehydrated in the store

Released 2026-08-13.

Fixed

• Regions handed to the store as JSON now render on every backend (jit-ui#124). A bounds that came through JSON.parse — a host's server response, a structuredClone — has the right fields but not the right prototype, and the renderers disagreed about whether that is acceptable: Region.getShape() (Plotly) and the napari overlay duck-type the bounds, while the OpenSeadragon overlay discriminates with bounds instanceof Rectangle. So a JSON region drew in Heatmap mode and silently vanished in Image mode.

  instanceof also gates the store's geometry de-duplication, moveRegion, and the GeoJSON export, so the same regions were undraggable, re-appended on every repeat, and missing from a save — in every mode, unreported because they were at least visible.

  RegionStore now normalizes on the way in (setRegions, addRegion, enterStackMode) via the exported hydrateBounds, so the ~20 instanceof call sites downstream stay valid rather than each having to duck-type. Instances are passed through by reference — overlays and tools mutate the bounds they created during a drag. hydrateBounds also fills in what a lean serializer omits (JIT's Java PolygonSerializer writes only npoints / xpoints / ypoints, while the GeoJSON export reads coordinates and the overlays read closed).
