Prevent triggering `subscribeChanges` when long-polling request finishes with `up-to-date`

I noticed in our app that every time a long-polling request finishes, it causes all associated queries on that collection to return a new data object. In React, this triggers a lot of unnecessary re-renders.

This appears to be because the snapshot version is bumped whenever subscribeChanges is called, even if the list of changes is empty.

db/packages/react-db/src/useLiveQuery.ts

Lines 390 to 394 in 59b406e

	const subscription = collectionRef.current.subscribeChanges(() => {
	// Bump version on any change; getSnapshot will rebuild next time
	versionRef.current += 1
	onStoreChange()
	})

When I patch @tanstack/react-db as below, the problem goes away.

Thanks for the report @evanob and the diff, it gave me a good lead to find the underlying issue. It's fixed in #604 and we should get that out in the next 24hrs.
