//! `--help` snapshot guard (15a): the committed snapshot is the contract
//! between the CLI surface and the docs (OPERATIONS.md, README). If this
//! test fails, the CLI changed — update the docs, then regenerate:
//!
//! ```bash
//! cargo run -q -p devflow -- --help > crates/devflow-cli/tests/snapshots/devflow-help.txt
//! ```
