 - Refactored handlers to use a util that codifies responses on calls.
 - Added documentation with luadoc types for improved linting.
 - Records are now returned as an alphabetically sorted array of [{name, transactionId, ttlSeconds}] with the '@' record being the first.
+- Removed `Evolve` handler and SourceCodeTxId from state and state responses.
