//! Core ECS (Entity Component System) module.
//!
//! This module provides the primary API surface for Sky Engine:
//!
//! - [`World`] — the central container for entities, components, and resources.
//! - [`EntityId`] — a generational handle to a live entity.
//! - [`ComponentAccessor`] / [`ComponentAccessorMut`] — bound random-access fast paths.
//! - [`CommandBuffer`] — an owned deferred buffer for manual structural changes.
//! - [`Commands`] — a borrowed deferred writer available as a system parameter.
//! - [`Bundle`] — trait implemented for component tuples used in [`World::spawn`].
//! - [`Query`] / [`QueryMut`] — world-bound typed query facades.
//! - [`PreparedQuery`] — an explicit reusable query plan for advanced hot paths.
//! - [`With`] / [`Without`] — archetype-level query filters.
//! - [`View`], [`ParView`], [`Res`], and [`Commands`] — inferred typed system parameters.
//! - [`StageLabel`] — type-level labels used by [`World::stage`].
//! - [`Time`] — per-frame timing information.
