`update` properly discovers and establishes new cycles.

``` unison
ping : 'Nat
ping _ = 1

pong : 'Nat
pong _ = !ping + 2
```

  I found and typechecked these definitions in scratch.u. If you
  do an `add` or `update`, here's how your codebase would
  change:
  
    ⍟ These new definitions are ok to `add`:
    
      ping : 'Nat
      pong : 'Nat

```
``` ucm
scratch/main> add

  ⍟ I've added these definitions:
  
    ping : 'Nat
    pong : 'Nat

```
``` unison
ping : 'Nat
ping _ = !clang + 1

clang : 'Nat
clang _ = !pong + 3
