claude_runner 1.4.1

//! `claude_runner` crate / `clr` binary — Claude Code CLI + command schema constants.
//!
//! This crate has two roles:
//!
//! 1. **Library** — exports [`COMMANDS_YAML`], the path to the `.claude` command schema,
//!    for use by YAML consumers at compile time or runtime.
//!
//! 2. **Binary** (`clr`) — Standalone CLI that mirrors Claude Code's native
//!    `--flag value` syntax and executes via `claude_runner_core`.
//!    Session continuation (`-c`) is applied by default when a prior session exists; use `--new-session` to start fresh.
//!
//! ## Two roles, two consumers
//!
//! ```text
//! clr binary (standalone CLI)
//!   invoked directly: clr "Fix bug" --dir /path --model sonnet
//!     → parse_args() → ClaudeCommand builder → claude subprocess (with -c when session exists)
//!   message given → print mode (default); bare clr → interactive REPL
//!
//! YAML consumers (e.g. consumer workspace's CLI, build.rs)
//!   aggregate: claude_runner::COMMANDS_YAML → registers .claude + .claude.help in PHF map
//! ```
//!
//! This lib has **zero consumer workspace dependencies**. Without `enabled`, it is a pure constants +
//! types crate. With `enabled`, it also exposes [`register_commands`] (API consistency shim).
//!
//! ## Registering commands in other binaries
//!
//! **Build-time (PHF):** Point `build.rs` at [`COMMANDS_YAML`].
//!
//! **Runtime:** Use `MultiYamlAggregator` with [`COMMANDS_YAML`].

  //   `clr run msg` does not treat "run" as the message argument.
  // Root cause: `clr run msg` treated "run" as the message argument — silent wrong behavior.
  // Pitfall: strip only the leading "run" token; remaining args are passed normally.
  //
  // Fix(BUG-215): stripping first also means the single help check below covers both
  //   `clr help` and `clr run help` — no need for two separate checks.
  // Root cause: `clr run help` bypassed the help dispatcher because `tokens[0]` was "run",
  //   not "help" — the help check never fired for the `clr run help` form.
