Remove Claude.md #5773

Creating a reference issue to remove CLAUDE.md once we're satisfied the majority of the contributor base who use Claude have moved onto a version that supports reading AGENT.md direct. The CLAUDE.md file is only a redirect to AGENTS.md so won't be needed.

I think a couple of months so should be enough.

I agree we don't need to let it hang around too long. Claude is generally pretty good at promoting users to upgrade, but as you can see from my example, not everyone is good at taking that advice 😄

I'll open an issue to remove the file in the future.
