//! Command-line surface: global flags, command tree, and dispatch.
//!
//! Kept in the library rather than in `main.rs` so tests can parse arbitrary
//! argument vectors -- in particular `tests/route_coverage.rs`, which checks
//! that every API route is reachable through a command that really exists.
