feat(deps): upgrade upstream dependencies (#786)

Automated daily upgrade of upstream dependencies:
- rolldown (latest tag)
- rolldown-vite (latest tag)
- vitest (latest npm version)
- tsdown (latest npm version)

Build status: success

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Primarily dependency upgrades, but they change the pack `--exe` output location/name (`dist` -> `build`), which can affect CLI behavior and downstream scripts/tests.
> 
> **Overview**
> Updates the bundled toolchain versions (notably `rolldown` to `1.0.0-rc.9` and `tsdown`/`@tsdown/*` to `0.21.2`), along with related lockfile and upstream hash bumps.
> 
> Adjusts the `vp pack --exe` snapshot tests to match new output behavior: executables are now produced and invoked from `build/index` (and test cleanup now removes both `dist` and `build`).
> 
> <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 6e51ea1. This will update automatically on new commits. Configure [here](https://cursor.com/dashboard?tab=bugbot).</sup>
