//! `hive-forge` — typed CLI wrapper around the in-cluster Forgejo's
//! REST API. Reads credentials from the environment:
//!
//!   `HIVE_FORGE_URL`      — base URL, e.g. `http://localhost:3000`
//!   `HIVE_FORGE_REPO`     — default repo, e.g. `hyperhive/hyperhive`
//!   `HYPERHIVE_STATE_DIR` — state dir; `forge-token` lives here
//!
//! Single binary with verb subcommands. Replaces the prior bash
//! script (`hive-forge-tools.nix`) so that agents and operators get
//! the same error handling, exit codes, and JSON shapes regardless
//! of how the bash mood was that day (closes #280).

#![warn(missing_docs)]
// Clap-derived `Args` structs are intentionally consumed by their
// per-verb `run` handler so we can move owned String fields out
// without cloning. The pedantic lint flags every one of them.
