shine-cli 2.0.0-rc.1

//! CLI assembly adapter for the frontend-neutral Core runtime.
//!
//! `rust-embed` and CLI configuration stay in this crate. Shared bootstrap
//! discovers external/overlay trees through the host port; every input used by
//! domain logic is captured before `CoreRuntime` is constructed.
