fix(ship,qa,document-release): repair proof-run regressions and fixture gaps

- ship-docsync-completion: yesterday's audit-scope result dropped the section's
  status, so /ship spliced one in; the section now opens with **Status:**.
- ship-docsync-missing-asset: a missing section or old Ship-owned mode blocks
  before launch.
- ship-docsync-late-result: the invocation record says prepare already saves
  the candidate selection (no extra Read; budget unchanged).
- qa exploratory: await the method Reads before the first probe.
- qa-callers fixture: quote the real review-log record template; allow the
  git log command plan-completion prescribes.
- qa functional observer: a receipt caught mid-link(2) is checked at stop
  instead of failing with ENOENT (reproduced from CI).
Each repaired case passed a focused paid run.
