Merging the Claude GitHub Actions install PR breaks `prettier --check .` CI

The workflow files added by the Claude Code GitHub app install PR (.github/workflows/claude.yml and claude-code-review.yml) are not Prettier-formatted. In a repo whose CI runs prettier --check . (for example a format:check script), every push to the default branch fails at the format step from that merge onward. The log names only those two files: [warn] .github/workflows/claude-code-review.yml. A local prettier --write . silently rewrites them too, so they show up as unrelated diffs in later work. Fix: run prettier --write on the two files once and commit that as a separate style commit, or add .github/workflows/claude*.yml to .prettierignore if you want to keep the generated text byte-for-byte for future app updates.
