refactor!: remove unnecessary contracts/deployments

Removing deployment artifacts

I'll share here how I removed specific contracts from the deployment artifacts. Take HistoryFactory as an example.

git ls-files | grep HistoryFactory | xargs git rm
for file in export/abi/*.json
do
  jq 'del(.contracts.HistoryFactory)' "$file" > tmp
  mv tmp "$file"
  git add "$file"
done

Don't mind the branch name feature/shared-history. Its meaning has been disassociated from the name, but we'll keep using it anyway.

You forgot to delete IHistory.sol.

Removing IHistory now would break Authority. We'll remove as soon as Authority no longer depends on it.
