Function insert_call_outcome_test 

pub fn insert_call_outcome_test(
    interpreter: &mut Interpreter,
    outcome: InterpreterResult,
    return_memory_offset: Option<Range<usize>>,
)

Available on crate features __fuzzing only.

Insert a call outcome into the interpreter state (for testing call_with_interpreter).

Mimics revm-handler’s insert_call_outcome: pushes success indicator, copies return data to memory, and returns unspent gas.
