+/// Spawn a networked entity with persistence enabled
+///
+/// Creates an entity with both NetworkedEntity and Persisted components,
+/// registers it in the NetworkEntityMap, and returns the entity ID.
+/// This is the single source of truth for creating networked entities
+/// that need to be synchronized and persisted across the network.
+///
+/// # Parameters
+/// - `world`: Bevy world to spawn entity in
+/// - `entity_id`: Network ID for the entity (UUID)
+/// - `node_id`: ID of the node that owns this entity
+///
+/// # Returns
+/// The spawned Bevy entity's ID
+///
+/// # Example
+/// ```no_run
+/// use bevy::prelude::*;
+/// use lib::networking::spawn_networked_entity;
+/// use uuid::Uuid;
+///
+/// fn my_system(world: &mut World) {
+///     let entity_id = Uuid::new_v4();
+///     let node_id = Uuid::new_v4();
+///     let entity = spawn_networked_entity(world, entity_id, node_id);
+///     // Entity is now registered and ready for sync/persistence
+/// }
