Description
I think we can support rewrite `abs(i) = 1` to `i = 1 or i = -1`🤔 further.

Contributor guide
Research direction
Start by locating PruningPredicate and the static-pruning rewrite logic in the DataFusion source; no specific file or test is named in the issue. Trace how equality predicates are rewritten, then add coverage showing that abs(i) = 1 becomes i = 1 or i = -1 and verify the pruning behavior.
