Electric collection utils are not typed in mutation functions

[godiagonal]

• I've validated the bug against the latest version of DB packages

Describe the bug
The collection.utils received in onInsert, onUpdate and onDelete of electricCollectionOptions is typed as UtilsRecord rather than ElectricCollectionUtils<T>. This makes it unsafe to call awaitTxId and awaitMatch.

To Reproduce

const todosCollection = createCollection(
  electricCollectionOptions({
    id: 'todos',
    getKey: (item) => item.id,
    shapeOptions: {
      url: '/api/todos',
      params: { table: 'todos' },
    },
    onInsert: async ({ collection }) => {
      // ❌ This is typed as UtilsRecord instead of ElectricCollectionUtils<T>
      collection.utils;
    },
  }),
);

// ✅ This is typed as ElectricCollectionUtils<T>
todosCollection.utils;

Expected behavior
I expect mutation functions in electricCollectionOptions to receive collection utils typed as ElectricCollectionUtils<T>.
