Aligning IIIF 3D Viewer with Presentation API 4 — converting legacy manifests at runtime

I aligned IIIF 3D Viewer with the IIIF 3D Technical Specification Group's Presentation API 4 draft (Scene / PointSelector / WKTSelector / PerspectiveCamera). Existing manifests authored against IIIF Presentation 3 with a project-local 3DSelector / camPos extension are funnelled through a runtime converter so the rest of the pipeline only deals with v4. This post records the diff, the conversion rules, and the implementation outline.
