Function any_effectful 

pub fn any_effectful<E: AsRef<str>>(
    inferred: &HashMap<String, BTreeSet<E>>,
) -> bool

Is the crate EFFECTFUL — does ANY function carry a real (non-Unknown) effect? Governs whether the caller emits the honest “nothing hidden” fallback (effectful, but nothing clears the bar) vs nothing at all (a genuinely effect-free crate).
