devflow 2.2.0

//! D-12 (`28-CONTEXT.md`, `28-06-PLAN.md` Task 2): CLI-boundary coverage of
//! `devflow start`'s combined resolution of the `--yes-ship` flag and a
//! `yes_ship` key in `devflow.toml`. All five behavior cases run through
//! `--dry-run` — a cheap, no-worktree observation point, matching
//! `phase7_cli.rs`'s `start_dry_run_annotates_until_stage` pattern.
//!
//! Does NOT set `DEVFLOW_YES_SHIP` here — env precedence is already covered
//! by `devflow-core`'s `config::tests::env_overrides_file_yes_ship`, and the
//! binary here runs as a separate process so this suite stays out of the
//! `ENV_MUTEX`-guarded unit-test convention.
