cordance-cli 0.1.1

//! Cordance CLI — library entry.
//!
//! All dispatch logic for the `cordance` binary lives here. The companion
//! `src/main.rs` is a thin shim that calls [`run`]. The umbrella package
//! [`cordance`](https://crates.io/crates/cordance) also calls into `run` so
//! `cargo install cordance` and `cargo install cordance-cli` install the
//! same binary.
//!
//! ## Subcommands
//! - `cordance init` — write `cordance.toml`.
//! - `cordance scan` — emit a Markdown report at `.cordance/scan-report.md`.
//! - `cordance pack` — compile the pack, emit every target.
//! - `cordance advise` — deterministic doctrine checks (no LLM).
//! - `cordance doctrine <topic>` — query engineering-doctrine.
//! - `cordance cortex push` — emit a `cordance-cortex-receipt-v1-candidate.json`.
//! - `cordance check` — drift detection vs `.cordance/sources.lock`.
//! - `cordance explain <rule>` — provenance of a generated rule.
//! - `cordance watch` — re-run pack on file changes.
//! - `cordance serve` — start the JSON-RPC MCP server (stdio).
//! - `cordance doctor` — pre-flight checks.
//! - `cordance completions <shell>` — emit shell completion scripts.
