Once v0.1.1 is release, rename the `main` branch to `v0.1-archive` and then rename `next` to `main`

We do not expect to add new feature to the original version of `hallmark`.
Once v0.1.1 with the updated ParaFrame is released, we should turn its branch to `v0.1-archive`.
We should then rename `next` to `main` and focus on development the new version.
