eval(plan-eng-review-artifact): periodic checkpoint resumes at Test review; the fresh full run moves to marathon

A fresh interactive /plan-eng-review cannot reach Test review inside the
600 s periodic budget: startup plus one-at-a-time Scope Challenge questions
took 595 s with six questions and no Test review in census 37174266054 and
in a local run (one earlier fresh run passed at 498 s). Per the eval-speed
policy, the long run moves to the non-blocking marathon lane and the
blocking case becomes a focused checkpoint.

- plan-eng-review-artifact (periodic, 600 s unchanged): resumes the real
  interactive skill from a saved review record: the plan, the Scope
  Challenge result, Sections 1-2 complete, and a Decision ledger rebuilt
  from that census run's six actual native questions and answers
  (test/fixtures/plan-eng-artifact-resume-37174266054.json). The live skill
  runs Section 3, Test review. Assertion unchanged: exactly one new
  eng-review test plan in the run's own state root, about the dashboard
  change. Paid trial (local, Claude Code 2.1.284): PASS, 364 s.
- plan-eng-review-artifact-full (marathon, PTY_LONG_MS): the fresh
  start-to-finish run with the same assertion; budget measured beside it.
- test/plan-eng-resume.test.ts proves the rebuilt record is a valid resume
  point and rejects missing, unanswered, edited or duplicated records.
- Registry: touchfiles, tiers, kinds, test-name labels, durations, paid
  file count 115, PTY consumer list; CHANGELOG and TODOS.
