Nuxt v5 / Nitro v3: unresolved import for `nitropack/runtime` during build

Environment

• Package: @nuxt/content 3.12.0
• Nuxt: https://pkg.pr.new/nuxt@95e6b9f
• Nitro: 3.0.260415-beta
• Vite: 7.3.1

Reproduction

Run pnpm build in a Nuxt v5 / Nitro v3 project using this package.

Actual result

The build emits UNRESOLVED_IMPORT warnings because the published runtime imports nitropack/runtime, which does not resolve in this setup.

[UNRESOLVED_IMPORT] Warning: Could not resolve 'nitropack/runtime' in node_modules/.pnpm/@nuxt+content@3.12.0.../node_modules/@nuxt/content/dist/runtime/presets/node/database-handler.js

import { useStorage } from "nitropack/runtime";

Affected file

• dist/runtime/presets/node/database-handler.js

Expected result

No unresolved import warnings when building with Nuxt v5 / Nitro v3.

Reference

Nuxt upgrade guide, migration to Nitro v3:
https://github.com/nuxt/nuxt/blob/main/docs/1.getting-started/18.upgrade.md#migration-to-nitro-v3

Reproduce the issue by running pnpm build in a Nuxt v5/Nitro v3 project using @nuxt/content. Inspect dist/runtime/presets/node/database-handler.js and compare its nitropack/runtime import with the Nitro v3 migration guidance. Done means the build emits no unresolved import warnings.
