<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Primarily dependency/version bumps and snapshot updates; risk is limited to behavior changes in upgraded tooling (lint/format/build) affecting CI output or developer workflows.
>
> **Overview**
> Updates upstream toolchain dependencies (notably `oxlint` 1.55→1.56, `oxfmt` 0.40→0.41, `tsdown` 0.21.3→0.21.4, and `@vitejs/devtools` 0.1.0→0.1.2) and refreshes `pnpm-lock.yaml`/workspace catalog pins accordingly.
>
> Refreshes CLI snapshot tests to match new tool output, including updated `--tsconfig`/`--import-plugin` help text and an additional config-load error line during `vp check --fix`.
>
> <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit d129e30. This will update automatically on new commits. Configure [here](https://cursor.com/dashboard?tab=bugbot).</sup>
