viewer.html: implement selector= parameter

Browse source 
applySelector() classifies elements via OBC.Classifier.byCategory(), then
maps the selector type names to matching categories using prefix matching
(so IfcWall also covers IfcWallStandardCase), and calls hider.isolate() to
show only matching elements. Supports simple type names and + union syntax.

{"id":"ifcurl-bab","title":"Implement clip= parameter in viewer.html","description":"The ifc:// spec defines a repeatable clip= parameter (6 floats: point x,y,z + normal x,y,z in IFC world coords). The Python ifcurl renderer handles it, but viewer.html ignores it entirely — no parsing, no Three.js clipping planes, no round-trip into the URL on camera sync. Implement: parse clip= from the ifc:// URL, apply as THREE.Plane clipping planes to the renderer (with IFC→Three.js coordinate transform), and include current clip planes when rebuilding the URL.","status":"open","priority":2,"issue_type":"feature","owner":"bruno@postle.net","created_at":"2026-04-24T05:45:58Z","created_by":"Bruno Postle","updated_at":"2026-04-24T05:45:58Z","dependency_count":0,"dependent_count":0,"comment_count":0}
