chore(contracts): Add binding check

[ethenotethan]

Why are these changes needed?

Adds a hygiene workflow which ensures that abi artifacts must be reflective of latest contract changes. Also noticed we were using two compilation commands (compile-el, compile-dl); these don't appear to have any instrumentation over the compile.sh script behavior so condensed into single compile-contracts target 😄
