governor-core 1.3.0

//! # cargo-governor core library
//!
//! This library provides the core domain and application logic for cargo-governor,
//! a Machine-First, LLM-Ready, CI/CD-Native release automation tool for Rust crates.
//!
//! ## Architecture
//!
//! The library follows Clean Architecture principles with four layers:
//!
//! 1. **Domain Layer** - Pure business entities and value objects
//! 2. **Traits** - Core abstractions for external dependencies
//! 3. **Application Layer** - Workflow engine, version analysis, changelog generation
//! 4. **Infrastructure** - Adapters for Git, Registry, etc. (separate crates)
//!
//! ## Modules
//!
//! - [`domain`] - Core domain entities (Version, Crate, Commit, Release, etc.)
//! - [`traits`] - Core traits for external dependencies

#![warn(missing_docs)]
#![forbid(unsafe_code)]
#![allow(clippy::multiple_crate_versions)] // Transitive dependency version conflicts are acceptable
