ci: skip claude review when its own workflow file is modified

The OAuth token exchange validates that the workflow file matches
main exactly, so PRs that modify claude-code-review.yml always fail.
Add an early check that detects this and skips the review gracefully
instead of burning runner time on an inevitable 401.

-            IMPORTANT: You MUST always post a PR comment, even if no issues are found.
-            Do NOT skip the review for any reason — never treat a PR as "trivial" or
-            "obviously correct." Always run the full review pipeline and post a comment
-            with the results. If no issues are found, post the "No issues found" summary.
