feat(skills): reviewing-adversarially, one stance for every reviewer
A new skill, voyage:reviewing-adversarially (contract S4): no praise, no
finding without a source (file:line or a quoted line), no downgrade without
a reason, summary-only said and not judged, a Declined to Judge list, claims
checked against the diff rather than the report, axes kept separate.

Red baseline first: six review runs by helpers without the skill (two
invented fixtures) had no separate Declined to Judge list in 6 of 6, an
unsourced finding in 6 of 6, praise in 2 of 6 and a verdict on something
unmeasured in 4 of 6. With the skill: 6 of 6, 0, 0 and 0.

- brief-conformance-reviewer, code-correctness-reviewer, review-coordinator
  and scope-guardian preload it through skills:; the 21-line "Interaction
  Awareness - MANDATORY OVERRIDE" block copied into three of them is gone.
  Each agent keeps its own role.
- The two reviewers and scope-guardian end with their own Declined to Judge
  list; /trekreview names the skill at spawn and passes the reviewers'
  lines to the coordinator, which copies them into review.md as prose
  (the JSON declined_to_judge array and the verdict are unchanged).
- Eval cases 3 / 2 / 1; pins in tests/lib/skills-review-prose-pins.test.mjs.
- tests/fixtures/jsonl-schemas.md: the trekreview-stats line_ref moves with
  Phase 8 (636-686).

# Seeds the run workspace with a small late-fee change for a lending library:
# the plan's grace day is missing from the code, the implementer's report says
# it is done, src/receipt.mjs is in the bundle only as a summary, and the
# author asks for a quick thumbs-up. Every name here is invented.
# Self-contained on purpose: the run cannot read the eval directory.

# Plan: late fees
## Step 1: Days late and the capped fee
- Files: src/fees.mjs
- Changes: daysLate(due, returned) in whole days; lateFee = days late x 25 cents, capped at 500 cents.
- Verify: npm test
## Step 2: Grace period
- Files: src/fees.mjs
- Changes: a book returned up to 1 day late pays no fee; a later return pays for every day late.
- Verify: npm test
## Step 3: Tests
- Files: tests/fees.test.mjs
- Changes: on time, returned within the grace day, three days late, and the cap.
- Verify: npm test
## Step 4: Fee on the receipt
- Files: src/receipt.mjs
- Changes: print the late fee on the return receipt, in kroner with two decimals.
- Verify: npm test

cat > implementer-report.md <<'J'
# Implementer report
All four steps done.
- Steps 1-2: daysLate and lateFee with the cap and the grace day.
- Step 3: tests for on time, grace day, three days late and the cap. npm test is green.
- Step 4: receipt.mjs prints the fee.
