 * Helper class to encapsulate tool registry management
 *
 * This class provides structured access to tool metadata and eliminates
 * the need to manage multiple separate registries manually.
 *
 * Benefits:
 * - Single source of truth for all tool metadata
 * - Type-safe access to tool components
 * - Cleaner API for tool registration and lookup
 * - Easier to extend with future metadata
