cleanlib-cli 0.1.1

//! Wrapper arg-parser end-to-end: re-validates that each of the 4 wrappers
//! emits the expected (ecosystem, name, version) tuple downstream of the
//! cli_matrix mock. Complementary to the per-wrapper unit tests inside
//! `src/wrappers/*.rs` — those exercise corner cases; this matrix proves
//! the wrappers compose with the live HTTP verdict path.
//!
//! NOTE: wrappers are NOT directly invoked here via `cargo run` (process
//! spawn would balloon CI runtime); instead we exercise the parser layer
//! and prove the same `(ecosystem, name, version)` tuple resolves the
//! mocked verdict. This is the integration-layer assertion sister to the
//! per-wrapper unit tests.
