quorum-cli 0.2.1

//! Phase 1B Stage 4 — non-interactive auth integration tests.
//!
//! Drives the `quorum` binary against a `mockito` Lippa server so we
//! exercise the full env-var → login → keyring round-trip without
//! touching real Lippa. The keyring is the `--no-keyring` file
//! fallback; we redirect its base dir (`APPDATA` on Windows,
//! `XDG_CONFIG_HOME` on Linux) into a tempdir so the tests are
//! hermetic against the host's OS keychain.
//!
//! ACs covered: 88, 89, 90, 91, 92, 127, 129.
