<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: adds a new CLI flag and updates snapshots; behavior change is limited to consumers who opt into `--root`, plus minor lockfile metadata updates.
> 
> **Overview**
> `vp pack` now exposes a new `--root <dir>` flag to set the root directory for input files, and the CLI help snapshot tests are updated accordingly.
> 
> The `pnpm-lock.yaml` is refreshed to include new deprecation metadata for some transitive packages.
> 
> <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 498e8b9. This will update automatically on new commits. Configure [here](https://cursor.com/dashboard?tab=bugbot).</sup>
