Describe the bug

Hello 👋

While building app based on Electric I've spotted that utils on collection aren't typed correctly - they fall back to untyped UtilsRecord. Before just reporting it - I verified it for every built-in collection that has custom utils whether it works and found out that it doesn't for a few more collections.

It doesn't have utils (so it works correctly):

• RxDB collection

It works correctly for:

• Local Storage collection
• TanStack Query collection

Utils aren't typed correctly for:

• Local only collection
• Electric collection
• PowerSync collection
• Trailbase collection

I've created a reproduction including every single of the above collections (except of rxdb which doesn't have custom utils), so it's easy to verify:

https://github.com/pawelblaszczyk5/tanstack-db-missing-collection-utils/blob/main/src/test.ts

As you can see on above screenshot, a few of these has generic UtilsRecord instead of correctly typed ones.

To Reproduce

Steps to reproduce the behavior:

1. Create Electric/Trailbase/PowerSync/localOnly collection
2. Try to access utils
3. Observe them being untyped (they're still there at runtime)

Expected behavior

Collection utils are correctly typed
