feat(deps): upgrade upstream dependencies (#1147)

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**
> Bumps several core build/tooling dependencies (e.g. `rolldown`, `tsdown`, `@oxc-project/runtime`), which can change bundling/build behavior despite being mostly version updates.
>
> **Overview**
> Updates upstream toolchain versions across the repo, including `rolldown` (to `1.0.0-rc.12`), `tsdown` (to `0.21.5`), and `@oxc-project/runtime` (to `0.122.0`).
>
> Adjusts `packages/core` peer/bundled dependency versions accordingly (including widening the `typescript` peer range to allow `^6.0.0`), refreshes the tracked upstream commit hash in `packages/tools/.upstream-versions.json`, and regenerates lockfiles (pnpm + Cargo) to reflect transitive updates (e.g. `picomatch`, `oxlint-tsgolint`, new `acorn-import-phases`).
