Replaces M2's single hardcoded NDC-space triangle with a real perspective pipeline: ICameraService/CameraService (fixed camera at (0,3,6) looking at the origin), a QuadRenderer marker component, and a Draw() that iterates world.Query<QuadRenderer>() to draw every such GameObject at its own WorldMatrix. Needed as the foundation for M3's gizmos, which have to map a screen-space drag onto a real 3D axis — a 2D quad and no camera can't support that. Two real bugs found and fixed empirically, not designed in from the start: - SystemAccessScope correctly threw on Draw() querying QuadRenderer without declaring Reads<QuadRenderer>() on its Schedule.Add registration — the safety net catching a real omission, exactly as designed. - UniformMatrix4 needed transpose:true, not false. System.Numerics.Matrix4x4 is row-major in memory; glUniformMatrix4fv with transpose=GL_FALSE reads that layout as column-major instead. With transpose=false the quad simply didn't render — no error, no crash, just a blank screen. Confirmed via a correctly perspective-foreshortened, texture-mapped quad after the fix. Also adds samples/WindowDemo/scene.json (a single Quad GameObject with a QuadRenderer) so the new pipeline has something real to draw, loaded via the existing --scene flag.
