/**
 * Git Service
 *
 * Provides mobile-native Git operations using isomorphic-git.
 * Integrates with expo-file-system for React Native compatibility.
 *
 * Usage:
 * ```typescript
 * import { GitService } from '@/services/git';
 *
 * // Clone a repository
 * const result = await GitService.clone({
 *   url: 'https://github.com/user/repo.git',
 *   dir: '/path/to/local/repo',
 *   credentials: { password: token },
 *   onProgress: (event) => console.log(event.phase, event.percent),
 * });
 *
 * // Get status
 * const status = await GitService.status({ dir: '/path/to/local/repo' });
 * ```
