P2E: reconcile parity docs with real verifiers + dogfood wiki (wj-1zm)

[gpxl]

Summary

Final bead of the OPT2+ parity arc — reconciles wijzer's documentation and CI
with the reality of the vendored-real-code approach, and validates the
rewritten /wijzer:init by dogfooding it on wijzer itself.

• Reconciliation: PARITY.md's "Verified by" column pointed at
  aspirational plan artifacts ("golden run (Phase 2)", "Phase-3 scenario").
  Every row now cites the actual verifier — tests/parity-crossvalidate.test.ts,
  the verbatim vendored update-noop.test.ts, the
  tests/build-disciplines.test.ts drift-lock, tests/check-format.test.ts.
  .github/workflows/parity-watch.yml now watches the full vendored spec
  set (adds src/constants.ts + src/agent/types.ts), drops the stale
  tests/noop.test.ts mapping, and its remediation text now drives the real
  re-vendor → regenerate → npm test flow instead of a hand-port workflow
  that no longer applies. README.md states Node is a dev/CI-only
  dependency — the plugin needs no node at user runtime.
• Test: tests/plugin-structure.test.ts drops two parity-restatement
  assertions (parity-first, wj-1s6) — that coverage now lives where the
  values are actually derived/enforced: tests/build-disciplines.test.ts
  (derivation-time) and tests/check-format.test.ts (format-gate
  enforcement).
• Dogfood wiki: new openwiki/ (quickstart, architecture/overview,
  parity/overview, skills/overview, .last-update.json) generated by running
  the rewritten /wijzer:init against wijzer's own repo, plus a ## OpenWiki
  pointer appended to CLAUDE.md linking to it.

Validation

• Golden-run validated two ways in isolated worktrees: dogfooded on wijzer
  itself (this PR's openwiki/) and separately against an unfamiliar
  Swift repo — both runs passed scripts/check-format.sh with ok:true.
• Both quality gates passed: code-quality agent (91 tests green, shellcheck
  clean, Fable-5 review) and this commit agent's independent re-run of
  npm test (91/91) and npm run lint (clean).

Commits

• c0dda6e docs: reconcile parity claims with real verifiers (P2E, wj-1zm)
• ad9788e docs: dogfood the rewritten /wijzer:init on wijzer itself (P2E, wj-1zm)

Merge policy

Per this repo's Agent Config: squash + delete branch, auto-merge on green
CI (no human approval gate). This PR is not being merged by the commit
agent — leaving that to pr-monitor/CI per policy.

Test plan

• npm test — 91/91 passed
• npm run lint — shellcheck clean
• Code-quality agent: PASS (prior to this commit)
• Golden-run check-format.sh — ok:true on wijzer and an unfamiliar Swift repo
• Manual verification
