refactor: Improve clarity

Sourcery suggested:

    In stats_collectors, using collectors.extend(generator) works but is
    less self-documenting than a direct list comprehension; consider
    assigning collectors = [collector(...) for collector in ...] to
    match the declared return type and improve readability.
