feat(viz): graph_layouts (radial/hierarchical/fixed) + viewport multi-select+lasso (issue 0049i)

Phase 1 — graph_layouts:
- New module cpp/functions/viz/graph_layouts.{h,cpp,md} v1.0.0
- layout_grid, layout_circular, layout_random (migrated from graph_force_layout.cpp)
- layout_radial: BFS rings from root, hop k -> circle of radius k*ring_spacing
- layout_hierarchical: Sugiyama-style heuristic (longest-path levels + barycenter ordering)
- layout_fixed: no-op
- All respect NF_PINNED. graph_layout_circular/grid kept as deprecated wrappers.

Phase 2-3 — graph_viewport v1.2.0:
- Multi-selection via state.selection (vector<int>); NF_SELECTED kept in sync
- Lasso: Shift+Drag on empty area; AABB hit-test on release
- Drag of N-selection: all selected pinned + moved by mouse delta
- Ctrl+click toggle, Esc clears selection
- Right-click on node -> on_context_menu callback
- Double-click on node -> on_double_click callback
- Helpers exposed: graph_viewport_clear/add_to/toggle/is_selected (own TU for tests)

Phase 4 — tests:
- test_graph_layouts: 12 cases / 364 assertions covering geometry, pin, edges
- test_graph_viewport: 5 cases for selection helpers (pure logic, no GL)

Phase 5 — demo (primitives_gallery):
- Layout combo (force/grid/circular/radial/hierarchical/fixed) + Apply button
- Right-click popup with Pin/Unpin/Add-to-selection
- Status overlay shows [N selected] when selection non-empty
- Updated golden images

Issue moved to dev/issues/completed/.

feat(cpp/tests): test_visual con png diff vs goldens (skip si vacio)

- png_diff.{h,cpp}: pixel_diff_ratio(path_a, path_b, channel_threshold) con
  stb_image. Devuelve PngDiffResult con pixels_total, pixels_different y
  diff_ratio. Si dimensiones difieren, diff_ratio=1.0.
- test_visual.cpp: invoca primitives_gallery --capture sobre tmpdir, compara
  cada PNG vs cpp/tests/golden/<demo>.png con tolerancia 1% pixels distintos
  (threshold 5/255 por canal). SKIPea con WARN si:
  * golden dir vacio (no hay goldens todavia)
  * binario primitives_gallery no construido
  * el binario falla al capturar (entorno sin GL)
- CMakeLists: registra test_visual con FN_TEST_GOLDEN_DIR, FN_TEST_GALLERY_BIN,
  FN_TEST_TMP_DIR y FN_TEST_REPO_ROOT (para que la captura corra desde la
  raiz del repo y resuelva paths relativos como sql_workbench's registry.db).
- golden/: 41 PNGs iniciales generados en este entorno (WSL +
  LIBGL_ALWAYS_SOFTWARE=1). Pueden regenerarse con cpp/scripts/update_goldens.sh.

Issue 0048.
