Check documentation coverage with AI

We should check we cover the same taxonomy in the new docs.

Related issue #39.

Last AI redirects check was performed when start-here.mdx was still a stub. @Gusarich, could you please repeat the check around December 1st, such that we'll hopefully get more non-stub articles until then and will have enough time to review all redirects once more :)
