Build status: failure

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Primarily dependency/lockfile updates; risk is limited to potential build/runtime regressions introduced by the upgraded toolchain packages.
> 
> **Overview**
> Upgrades `@vitejs/devtools` from `0.0.0-alpha.33` to `0.0.0-alpha.34` in `packages/core`, with corresponding `pnpm-lock.yaml` updates to the `@vitejs/devtools-*` suite.
> 
> Lockfile also rolls forward related transitive versions (notably `@rolldown/debug` `rc.7`→`rc.8`, `h3` `1.15.5`→`1.15.6`, and `vue-virtual-scroller` `beta.8`→`beta.9`), drops `vue-observe-visibility`/`vue-resize` entries, and adds `vue-virtual-scroller` to `minimumReleaseAgeExclude` in `pnpm-workspace.yaml`.
