fix(bump): guard sibling-mismatch detection behind check_consistency, preserve trailing whitespace

* skip _LIKELY_VERSION_VALUE_RE.search and inconsistent_lines tracking when check_consistency=False, so the legacy fast path stays unchanged as the PR claimed

* use rstrip('\r\n') instead of rstrip() so the reported line content matches the actual file content (preserves meaningful trailing whitespace)
