Next 15 does not work if there is an instrumentation.ts file

### Verify Next.js canary release

- [x] I verified that the issue exists in the latest Next.js canary release

### Describe the bug

The server crashes on startup while trying to compile the `instrumentation.ts` file.

```
○ Compiling /instrumentation ...
⨯ ./instrumentation.ts
Error: × failed to invoke plugin on 'Some("/project/workspace/instrumentation.ts")'
[Error: An error occurred while loading instrumentation hook: Cannot find module '/project/workspace/.next/server/instrumentation'
Require stack:
- /project/workspace/node_modules/.pnpm/next@15.3.0-canary.24_react-dom@19.0.0_react@19.0.0/node_modules/next/dist/server/dev/next-dev-server.js
- /project/workspace/node_modules/.pnpm/next@15.3.0-canary.24_react-dom@19.0.0_react@19.0.0/node_modules/next/dist/server/next.js

code: 'MODULE_NOT_FOUND',
requireStack: [Array]
```

### Expected behavior

The server to startup normally and the superjson plugin to function.

### Version

0.6.3

### Config

```javascript
{
reactStrictMode: true,
experimental: {
swcPlugins: [["next-superjson-plugin", {}]],
},
}
```

### Additional context

If you delete the `instrumentation.ts` file OR the superjson plugin line from next config, everything works normally.
