0e01067d55 feat: Allow queries to avoid panics on cycles
Quickest POC I could create to get some potentially cyclic queries to
not panic and instead return a result I could act on. (gluon's module
importing need to error on cycles).

```
// Causes `db.query()` to actually return `Result<V, CycleError>`
fn query(&self, key: K, key2: K2) -> V;
```

A proper implementation of this would likely return
`Result<V, CycleError<(K, K2)>>` or maybe larger changes are needed.

21a70b6eb0 use a newtype'd IsConstant for better readability
Random bool constants are just so gauche.
