Two small QoL improvements inspired by feedback:
* `if (ref.current == undefined) { ref.current = ... }` is now allowed.
* `if (!ref.current) { ref.current = ... }` is still disallowed, but we emit an extra hint suggesting the `if (!ref.current == null)` pattern.
I was on the fence about the latter. We got feedback asking to allow `if (!ref.current)` but if your ref stores a boolean value then this would allow reading the ref in render. The unary form is also less precise in general due to sketchy truthiness conversions. I figured a hint is a good compromise.
