(feat): Tanstack Query Sync Streams

[Chriztiaan]

This PR adds sync stream support to the tanstack react query package, you can now define sync streams when calling useQuery and useQueries.

Examples:

useQuery({ queryKey: ['test'], query: 'SELECT 1', streams: [db.syncStream('a')] });

useQueries({
    queries: [
        { queryKey: ['test1'], query: 'SELECT 1', streams: [{ name: 'a' }] },
        { queryKey: ['test2'], query: 'SELECT 2', streams: [{ name: 'b' }] }
    ]
});

Verification:

• Added unit tests
• Manually tested these hook changes in the Supabase Todolist Sync Stream demo.
