New feature - get error at multiple named import

For better code split and tree shake, need this to warn/error

```
// WANT THIS
// not ok
import { a, b } from 'package'

// ok
import { a } from 'package/a'
import { b } from 'package/b'
```

but have this (want Inverted(?) group-exports rule)


If possible, with regex, to ignore selected packages (like react, storybook, @types, etc)

The issue names no files or tests, so first locate the existing rule or entry point that checks grouped imports and review its current behavior. Done should be a warning or error for multiple named imports from one package, while allowing separate subpath imports and configurable package exclusions.
