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/.
