dodot-lib 0.10.0

//! Public command API — the entry points for all dodot operations.
//!
//! Each function returns a `Result<T>` where `T: Serialize`. These
//! types are the contract with standout's rendering layer — they
//! carry everything needed to produce both human-readable (template)
//! and machine-readable (JSON) output.
