What's Wrong?

Body:
Session-ID: session_013EXdL7Du2PQgMVEpDWvzQD

Setup:

• Cherry-picked 201 commits from initial-commit onto a review-branch

(review-full-verwaltbot)

• /ultrareview launched with comparison "review-full-verwaltbot → main"
• Cherry-pick produced content-identical commits → diff vs main = empty
• Cloud-review completed in ~20s with 0 findings on ostensibly 731 files / 131k LOC

Expected: either bundle-rejection ("no effective diff") or successful review of the
diff-vs-base
Actual: free run consumed, no review-value delivered

Request: Free-run restitution + clearer documentation/error when diff vs comparison-target
is empty after bundling
