//! Visibility action builder for controlling entity visibility
//!
//! This module provides a builder for visibility actions, which control
//! whether entities are visible to graphics systems, sensors, and traffic.
//!
//! # Usage Examples
//!
//! ```rust
//! use openscenario_rs::builder::actions::visibility::VisibilityActionBuilder;
//!
//! // Make entity fully visible
//! let visible_action = VisibilityActionBuilder::new()
//!     .for_entity("ego_vehicle")
//!     .visible();
//!
//! // Make entity invisible
//! let invisible_action = VisibilityActionBuilder::new()
//!     .for_entity("ego_vehicle")
//!     .invisible();
//!
//! // Custom visibility settings
//! let custom_action = VisibilityActionBuilder::new()
//!     .for_entity("ego_vehicle")
//!     .graphics(true)
//!     .sensors(false)
//!     .traffic(true);
//! ```
