Alert class

A fluent builder for creating styled alerts.

Provides a chainable API for alert configuration with support for the new Style system, custom borders, and multiple display styles.

final alert = Alert()
    .info()
    .message('Operation completed successfully!')
    .displayStyle(AlertDisplayStyle.block)
    .render();

print(alert);

// Or with custom styling
final customAlert = Alert()
    .message('Custom alert')
    .prefix('[CUSTOM]')
    .prefixStyle(Style().bold().foreground(Colors.magenta))
    .messageStyle(Style().italic())
    .render();
