bug: filtering on boolean columns

[kevin-dp]

Tanstack DB currently doesn't support boolean columns as filters. We often end up having to write filters like this:

const { data: products } = useLiveQuery(q =>
    q.from({ product: productCollection })
      .where(({ product }) => product.in_stock)  // Use computed field
      .where(({ product }) => eq(product.in_stock, true))
)

This isn't idiomatic since product.in_stock is already a boolean so we should be able to just write where(({ product }) => product.in_stock). And similarly we often end up writing negations as eq(product.in_stock, false) instead of the more idiomatic not(product.in_stock).
