Neuer GPU-Renderer fuer den Grundriss (src/plan/glPlan/): Earcut-Tessellierung (konkav-faehig), gehrte Linienzuege (Miter), echte Papier-mm-Strichbreiten im Massstab (repliziert den SVG-printStrokeVb-Pfad), Hybrid mit scharfem SVG-Text- Overlay. GPU ist der Standardpfad; der SVG-Renderer bleibt automatischer Fallback, falls WebGL2/Shader nicht verfuegbar sind. Imperativer Pan (rAF + CSS-transform) fuer fluessige Interaktion ohne React-Re-Render je Frame. Enthaelt zudem den bisher nicht committeten Arbeitsstand des Browser-BIM (Oeffnungen, Treppen, Raeume, Decken, DXF-Export, Materialbibliothek, Kontext- Import, Tauri-Compute-Boundary-PoC).
