<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Dependency-only update (no runtime code changes), with minimal risk aside from potential upstream tooling behavior changes from the `@vitejs/devtools`/`rolldown` updates.
> 
> **Overview**
> Updates the `@vitejs/devtools` dependency in `packages/core` from the `0.0.0-alpha.34` line to `^0.1.0`.
> 
> Regenerates `pnpm-lock.yaml` to pull in the corresponding `0.1.0` devtools subpackages and bumps `@rolldown/debug` from `1.0.0-rc.8` to `1.0.0-rc.9`, updating `tsdown`’s resolved optional devtools peer accordingly.
