- tsdown (latest npm version)

Build status: success

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk dependency-only update, but it may introduce build/test behavior changes due to Vite/Vitest version bumps and related transitive upgrades.
>
> **Overview**
> Updates bundled/toolchain dependency versions: **Vite** is bumped from `8.0.2` to `8.0.3`, and **Vitest** (plus all `@vitest/*` packages and `vitest-dev`) from `4.1.1` to `4.1.2`.
>
> Refreshes upstream pinning (`packages/tools/.upstream-versions.json`) and lockfile/workspace overrides to match the new versions, including related transitive bumps like `tinyrainbow` and `flatted`.
>
> <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 555218c. This will update automatically on new commits. Configure [here](https://cursor.com/dashboard?tab=bugbot).</sup>
