ci: checks fail for me on changes after initial PR submission.

See this comment and this commit, which fixes the first issue for me.

The subsequent gh-pages issue seems related to this.

Strangely, there is no [x] on the PR or the commits that fail. The only way I get any notice and can find the build log is by email.

The subsequent gh-pages issue seems related to r-lib/pkgdown#1223.

This should be no problem as I removed the bench workflow in ab32905, since it was not being used anymore.

I also added a skip checking for the normal CI workflow (clippy and test); This will prevent workflows from being duplicated in pull requests, and will cancel outdated workflows if you push new commits on the same branch.

About some workflows not being executed when a push is made, I think this is related to forced push only, and I don't know how to fix it.

thx, I will reopen if I see further weirdness.
