feat(ship): version-less repos, docs-audit record and caps, the frozen-scope paid case, and the review-loop follow-ups

Follow-up to the review-loop convergence PR: Step 12 and the CHANGELOG step skip cleanly in a repository with no version source (receipt version "none"); the receipt records the docs audit outcome and the owner exception (DOCS_AUDIT_BLOCKED without one) and a policy may declare doc caps (gstack-ship-receipt docs-caps); docs/unattended.md names the READY evidence and the cross-family outside voice; the ship-frozen-scope-convergence behaviour case runs the generated Step 9.4 under review_scope frozen through the real binaries; carry probes git >= 2.39 (RECEIPT_GIT_TOO_OLD); defer passes the repository to gh repo view positionally and names its search limit; late defers count without being passes; reviewers diff from RANGE_BASE on pass 2+; the cap check runs before edits; --review-fanout batches specialists by free slots; read --check-prose compares quoted counters with the receipt (RECEIPT_PROSE_MISMATCH); checklist rule ids prereg-with-results and test-keyboard-count-loop; gstack-coauthor-trailers.
