fix(ship): always run the design-lite detector probe; test(shared-libs): credit a failed first file view and deferred-reuse Skip wording

- /ship design-lite: the probe is mandatory and any non-ready first line is
  stated, matching /review (5 of 6 captured /review trials had skipped it).
- shared-libs-pr-coverage: the first PR 42 page-1 read printed only a jq error,
  so the one refetch is a legitimate recovery, charged to the same budget.
- shared-libs-review-prior-coverage: the Skip option said a future review can
  "reuse it once snapshot coverage holds"; a conditional tail on the recorded
  decision is not product work. Captured-text regressions and negative controls.
