moonlit-pdk 0.2.0

//! Exercises the `moonlit_plugin!`-generated `Guest` impl natively (host target).
//! The generated code uses `__MoonlitUnavailableHost` off-wasm, so we assert on
//! init metadata, the middleware list, and unknown-middleware dispatch — paths
//! that do not depend on host calls.
