registry/indexer.go ahora escanea <lang>/apps/*/app.md ademas de apps/ y projects/*/apps/. cpp/apps/chart_demo y cpp/apps/shaders_lab pasan a estar en registry.db con sus manifests. Infraestructura de tests e2e (opt-in con -DFN_BUILD_TESTS=ON): - vendor de Dear ImGui Test Engine (personal/open-source license). - chart_demo_tests target con tests/chart_demo_tests.cpp. - /e2e-cpp slash command para crear y ejecutar tests e2e.
