In a future fork, light client data will be extended with execution info to support more use cases. To anticipate such an upgrade, introduce `Forky` and `Forked` types, and ready the database schema. Because the mapping of sync committee periods to fork versions is not necessarily unique (fork schedule not in sync with period boundaries), an additional column is added to `period` -> `LightClientUpdate` table.
