cargo-rail 0.13.4

//! CLI commands for cargo-rail
//!
//! This module contains all user-facing command implementations:
//!
//! ## Dependency Unification
//! - **unify**: Eliminate workspace-hack crates via native workspace dependency unification
//!
//! ## Configuration Management
//! - **init**: Initialize cargo-rail configuration (rail.toml)
//! - **config**: Validate and manage configuration
//!
//! ## Split & Sync
//! - **split**: Split monorepo crates to separate repositories
//! - **sync**: Bidirectional sync between monorepo and split repos
//!
//! ## Inspection
//! - **plan**: Deterministic file-first planner (primary planning surface)
//! - **run**: Surface-driven executor using planner contract
//!
//! All commands accept `&WorkspaceContext` to avoid redundant workspace loads.
