/**
 * DependencyService — Implements IDependencyService for dependency analysis and validation.
 *
 * Key design decisions:
 * - Single class replaces CLI's DependencyService + DependencyAnalyzer + DependencyValidator
 * - Recursive tree building with circular dependency detection (visited + visiting sets)
 * - No internal caching (session-scoped, repos handle caching)
 * - Max recursion depth: 10
