//! `ebman <verb>` non-interactive subcommands.
//!
//! Pre-0.15 every `run_*_cli` lived as an inline `async fn` in
//! `src/main.rs`, which ballooned to 2,600+ lines as the CLI surface
//! grew (audit/explain/lint --fix all landed in 0.14). The 0.14
//! architecture review's #1 finding was the resulting grab-bag.
//!
//! Each verb now lives in its own file under `src/cli/`, exposing
//! `pub async fn run(args: &[String]) -> Result<()>`. `main.rs`
//! dispatches by argv[1] and calls the matching `cli::<verb>::run`.
//! Shared CLI-only helpers (the `decide_poll` state machine, the
//! `--fix` dispatch-failure flag, the JSON-string escaper, the
//! cli-arg escaper) live here in `mod.rs`.
//!
//! Convention:
//! - Each module is named after the subcommand (`audit.rs`,
//!   `explain.rs`, ...) and exports exactly one public function:
//!   `pub async fn run(args: &[String]) -> Result<()>`. `args` is
//!   the full `std::env::args()` vector so callers can index from
//!   `args[1]` onwards uniformly.
//! - Exit codes follow the 0.13 CLI charter (locked in
//!   `BACKLOG.md`): 0 ok, 1 aws err, 2 usage err, 3 issues / drift,
//!   4 wait-for-green timeout, 5 auto-rollback fired.
//! - No `println!` inside the TUI alternate screen — these
//!   subcommands run before / outside TUI lifecycle, so plain
//!   stdout/stderr is fine.
