openglfx-jogl does not declare JOGL; the GUI now uses com.jogamp.opengl
directly, so depend on jogl-all-main + gluegen-rt-main explicitly (versions
managed by parent; -main artifacts bundle platform natives).

Implements SceneBuilder with fromPolygons() and build() entry points,
plus private helpers for center computation and base color selection.
Test loads real GML fixture (building with BoundarySurfaces) to verify
buffer length consistency and that all picking ids resolve to Polygons.

OpenGLCamera/UniformLocation were a partial earlier attempt; superseded by
the new gui.gl package per docs/superpowers/plans/2026-06-18-opengl-3d-view.md.

Adds a generalized version of the 3D-Renderer LoadingDialog to improve
UX by showing that CityDoctor is currently busy doing something in the
background of indeterminate length, e.g. opening a file or waiting for
the Schematron thread to finish.

Adds the CppTest marker-interface to exclude Healer tests that  were
interfacing with CGAL from the build. These tests are needed for the
development of the replacement library, but shall not cause build
failures in the meantime.
