Happy to do the same for you if you want.
The quickest win in your case: map all the backlinks the .net site got (happy to pull this for you), then email every publication that linked to it. "Hey, you covered NanoClaw but linked to a fake site, here's the real one." You'd be surprised how many will actually swap the link. That alone could flip things.
Beyond that there's some technical SEO stuff on nanoclaw.dev that would help - structured data, schema, signals for search engines and LLMs. Happy to walk you through it.
update: ok this is getting more traction than I expected so let me give some practical stuff.
1. Google Search Console - did you add and verify nanoclaw.dev there? If not, do it now and submit your sitemap. Basic but critical.
2. I checked the fake site and it actually doesn't have that many backlinks, so the situation is more winnable than it looks.
3. Your GitHub repo has tons of high quality backlinks which is great. Outreach to those places, tell the story. I'm sure a few will add a link to your actual site. That alone makes you way more resilient to fakers going forward. This is only happening because everything is so new. Here's a list with all the backlinks pointing to your repo:

4. Open social profiles for the project - Twitter/X, LinkedIn page if you want. This helps search engines build a knowledge graph around NanoClaw. Then add Organization and sameAs schema markup to nanoclaw.dev connecting all the dots (your site, the GitHub repo, the social profiles). This is how you tell Google "these all belong to the same entity."
5. One more thing - you had a chance to link to nanoclaw.dev from this HN thread but you linked to your tweet instead. Totally get it, but a strong link from a front page HN post with all this traffic and engagement would do real work for your site's authority. If it's not crossing any rule (specific use case here so maybe check with the mods haha) drop a comment here with a link to nanoclaw.dev. I don't think anyone here would mind if it will get you few steps closer towards winning that fake site
