dakera-client 0.11.90

//! Integration tests against a real Dakera server (Docker service in CI).
//!
//! Requires DAKERA_TEST_URL env var pointing to a running Dakera instance.
//! Auth is enabled — set DAKERA_API_KEY to a valid key (default: test-key).
//!
//! Run locally: DAKERA_TEST_URL=http://localhost:3000 DAKERA_API_KEY=test-key cargo test --test integration_test
