feat(deps): upgrade upstream dependencies (#1334)

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

Build status: success

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Moderate risk due to multiple toolchain dependency upgrades (Vite/Vitest/Oxlint/Oxfmt) and lockfile churn, which can impact build/test behavior. Code changes are mostly type/return-value fixes with low functional impact but touch CLI build/migration paths.
>
> **Overview**
> Upgrades the upstream toolchain versions, including **Vite `8.0.6`**, **Vitest `4.1.3`** (adding coverage peer deps), and bumps **Oxlint/Oxfmt** across the workspace (with corresponding lockfile and upstream hash updates).
>
> Separately, tightens TypeScript behavior across CLI/core build utilities by consistently returning `undefined` from optional-return functions/plugins, adjusts prompt validation/render defaults, and makes minor prompt/test fixes (e.g., `select-key` label handling and a `writeFile` mock type tweak).
