That sounds very odd and very contrary to my experience. You don’t say which model you actually used, but I never had opus 4.8 (or sonnet for that matter) ignore which language/stack i wanted to use.
I stopped updating CLAUDE.md because I felt like Claude always ignored it. But over time I noticed there is still times (especially during planning and review) where it's good to maintain the official document as a reference. As opposed to memory.md or manual edits.
