/**
 * Playwright end-to-end smoke test
 *
 * Preconditions (operator must supply):
 *   - The backend is running on port 8080 with the built UI served via --webui-dir
 *   - SVAPI_ADMIN_KEY env var contains the admin API key (e.g. "e2eadmin")
 *   - SVAPI_BASE env var (optional) overrides the base URL (default http://localhost:8080)
 *
 * Run sequence (example):
 *   cmake --build build -j"$(nproc)"
 *   SMARTBOTIC_VECTORAPI_KEY=e2eadmin ./build/src/smartbotic-vectorapi \
 *     --config config/config.json --share-dir api --webui-dir build/webui/dist &
 *   cd webui && SVAPI_ADMIN_KEY=e2eadmin SVAPI_BASE=http://localhost:8080 npx playwright test
 *
 * The test creates a collection "e2e_docs" and a document inside it, then
 * deletes the collection (cleanup) before logging out.
