Please just dump the code into your github repo, messy as it may be. Code is never perfect.

By dumping, you'll retain all credit as main author as it will live on under your github name. (This won't happen if any unofficial github code-dump takes off). It will also reduce your work as people fix their own bugs and open PRs, all you have to do then is review and click "merge". So you can focus on implementing more interesting features.
