Add "has uid" as condition

why do we want this? at a high level I was hoping to abstract away uids from the user - they usually are trying to query by some other property of a block and not by its id.

at a base level, I'd probably prefer has block reference or something like that

I've reached for this a few times, but I forget the exact use cases for all of those.
But one specifically is with a smartblock workflow of pasting text into the current block:

• if current block has ancestor that references a link, append that link to the pasted text
