// A NON-integral float (`4.5`) as an `inline for` range bound is a hard error:
// the loop cursor must be a compile-time integer, so only an integral float
// (`4.0`, `-2.0`) folds. Clean diagnostic + non-zero exit.
//
// Regression (F0.4 attempt 11, Agra ruling): range bounds are exempt from the
// count negative-rejection (negatives are valid endpoints), but the
// must-be-integer requirement still applies — `4.5` has no integer value.
