//! Plugin-protocol smoke test — issue #46 acceptance item 2.
//!
//! End-to-end validation that the `klasp-plugin-pre-commit` reference plugin
//! (in `examples/klasp-plugin-pre-commit/`) builds standalone (no klasp-core
//! dep) and speaks the v0 plugin protocol via `--describe`. This proves
//! third-party plugin viability against the real binary, not a mock.
//!
//! Pass/fail gate-dispatch behaviour against mock plugins is already covered
//! by `klasp/tests/plugin_protocol.rs`; this file does NOT duplicate that.
