Function yes_ship 

pub fn yes_ship(project_root: &Path) -> bool

Resolve the Ship gate’s standing pre-authorization (D-12) with DEVFLOW_YES_SHIP taking precedence over devflow.toml and the built-in false default. Mirrors external_verify_enabled’s resolver shape exactly. Note that this resolver is not the only path by which state.yes_ship becomes true — commands::start also ORs in the --yes-ship CLI flag; this function reports only the config/env-derived half of that combination.
