Compute the before-state of diffs.
...
This is `Optional`, as some diffs have unrecoverable before states. For
example, the insertion of a term has no before state, but can still
produce a valid before state if it occurs within the context of an
`Indexed` or `Keyed` node.
However, certain malformed diffs (such as `.Pure(.Insert(…))` in
isolation) may lack a valid before state, and thus the public API has
to reflect this.
