PE: some sort of overflow with nondeterminstic builtins?

Still investigating 🔍 

`filters.rego`:
```rego
package filters
include if input.fruits.expiry > time.now_ns()
```

Observe:
```
$ opa eval -fpretty -p -d filters.rego --nondeterminstic-builtins data.filters.include
+---------+--------------------------------------------+
| Query 1 | input.fruits.expiry > -6795364578871345152 |
+---------+--------------------------------------------+
