/**
 * @fileoverview Subagents Phase 1 implementation - File-based configuration layer
 *
 * This module provides the foundation for the subagents feature by implementing
 * a file-based configuration system that builds on the existing SubAgentScope
 * runtime system. It includes:
 *
 * - Type definitions for file-based subagent configurations
 * - Validation system for configuration integrity
 * - Runtime conversion functions integrated into the manager
 * - Manager class for CRUD operations on subagent files
 *
 * The implementation follows the Markdown + YAML frontmatter format , with storage at both project and user levels.
