/// The code that builds the [`Context`] sets this value. The default is [`NonInteractive`], so
/// a context reports a user only when that code found one.

/// # Examples
///
/// ```
/// use clawless_core::context::Interactivity;
///
/// let interactivity = Interactivity::default();
/// assert_eq!(interactivity, Interactivity::NonInteractive);
/// ```
///
/// [`Context`]: super::Context
/// [`NonInteractive`]: Interactivity::NonInteractive
