/**
 * CLI plugin for vendoring Alepha packages into external projects.
 *
 * Copies package source code from a git remote into the current project's
 * `packages/` directory. Useful for corporate projects that need a local
 * copy of Alepha for AI tooling, audits, documentation, or quick fixes.
 *
 * Commands:
 * - `alepha vendor sync`  — replace local packages with remote source
 * - `alepha vendor diff`  — compare local packages against remote HEAD
 *
 * Configuration in `alepha.config.ts`:
 *
 * ```typescript
 * import { vendor } from "alepha/cli/vendor";
 *
 * export default defineConfig({
 *   plugins: [
 *     vendor({
 *       branch: "main",
 *       packages: ["alepha", "@alepha/payments-stripe"],
 *     }),
 *   ],
 * });
 * ```
