feat(linkedin): v2.4.0 — editorial-reviewer agent + Step 5.5 craft gate in /linkedin:newsletter

Endring 8 from the change spec (Del 4 production, Maskinrommet). The persona
resonance sweep measures reader-response (does it land?); nothing measured prose
craft or narrative architecture (is it well-made?). In Del 4 every persona
reported PASS, yet the editor found 8 fresh editorial points on first reading —
~6/8 craft/architecture blind spots no agent could see. v2.4.0 adds the missing
editor role.

New Step 5.5 (editorial-review) runs between fact-check (Step 5) and the persona
sweep (Step 6): a new editorial-reviewer agent (Opus) judges two axes —
prosa-handverk (em-dash density, verbatim repetition, postulated numbers,
contradictions, versal-tic) + narrativ-arkitektur (concrete instantiation,
theory-anchored hypotheses, series-title symmetry, equal action per addressee,
un-overloaded conclusion). Returns <=10 flags as direction (never copy), each
BLOCK/REWORK/NICE, operator-gated via SendUserFile. Runs before the persona
sweep so the personas measure resonance instead of stumbling on craft noise.
Mirrors the Maskinrommet writing-contract section C2 (bidirectional mirror rule).

- agents/editorial-reviewer.md (NEW, Opus, orange) + fasit fixture
  (editorial-reviewer-cases.md: Del 4 v5 gold standard, 8 points -> 2 axes +
  severities, 3 BLOCK / 5 REWORK, 6/8 blind spots) + structural lint (7 tests).
- Step 5.5 wired into commands/newsletter.md; pipeline 14 -> 15 phases.
- editorial-review phase + additive editorialReview state in
  config/edition-state.template.json; resumption: factcheck-sweep -> Step 5.5,
  editorial-review -> Step 6 (spec said fact-check; canonical key is
  factcheck-sweep).
- persona-reviewer contract unchanged: editorial-reviewer is supplementary
  (one measures craft, one measures response).
- All doc levels synced (plugin + root README/CLAUDE.md, CHANGELOG, plugin.json
  2.3.0 -> 2.4.0; agents 15 -> 16). 94 tests green.

Acceptance-criterion #8 (live run on Del 4 v5) delivered as fasit fixture:
a live run needs a session reload (new agent not invokable until then) + read
access to the Del 4 v5 draft in Maskinrommet.

-v2.3.0 makes **visual assets an explicit pipeline phase** in `/linkedin:newsletter`: new **Step 7.5 (visual-assets)** between annotation (Step 7) and lock (Step 8). The cover (+ optional inline figures) or a carousel deck is generated (default `mcp-image`; external `cover-raw.png` accepted) and operator-gated via `SendUserFile` **before lock**, so `render/build-linkedin.mjs` picks up `cover.png` + the edition-config credit/caption at lock without a post-lock re-render. Pipeline 13 → 14 phases; new `config/image-credit-caption.template.md` + additive `visualAssets` state; doc/orchestration-only (no new code). v2.2.0 **hardened the longform gates** with the lessons from the second production run (Seres-serien): the persona gate is **blocking with an explicit hard-fail list** (primær «mistet meg» / doesn't own the action / sjargong-mur / modell-/navne-katalog → BLOCK); fact-check is **orthogonal to narrative strength** with a **post-cutoff web-search mandate**; a **`voice-scrubber`** agent (Opus) does de-AI scrub + Norwegian-chronicle voice-drift correction; operator gates became **render+annotate** rounds; and per-edition state was **reconciled with the global STATE.md** continuity system (`edition-HANDOVER.md` removed). Commands unchanged (24); 15 agents. v2.1.0's skeleton-gate-before-prose and v2.0.0's full-spectrum surface are preserved. Updated for the January 2026 360Brew algorithm change, which validates your creator profile before distributing content.
+v2.4.0 adds an **editor's craft gate as an explicit pipeline phase** in `/linkedin:newsletter`: a new **`editorial-reviewer` agent** (Opus) + **Step 5.5 (editorial-review)** between fact-check (Step 5) and the persona sweep (Step 6). It judges **craft** — **prosa-håndverk** (em-dash density, verbatim repetition, postulated numbers, contradictions, versal-tic) + **narrativ-arkitektur** (concrete instantiation, theory-anchored hypotheses, series-title symmetry, equal action per addressee, un-overloaded conclusion) — not reader-response, returning **≤10 flags** (BLOCK / REWORK / NICE) as *direction* (never copy), operator-gated via `SendUserFile`, mirroring the Maskinrommet writing-contract §C2. Motivated by the Del 4 run, where **every persona reported PASS yet the editor found 8 fresh points on first reading, ~6/8 of them craft/architecture blind spots no agent measured.** Pipeline 14 → 15 phases; 15 → 16 agents; additive `editorialReview` state. v2.3.0 made **visual assets an explicit pipeline phase** (Step 7.5, between annotation and lock): the cover (+ optional inline figures) or a carousel deck is generated (default `mcp-image`; external `cover-raw.png` accepted) and operator-gated via `SendUserFile` **before lock**. v2.2.0 **hardened the longform gates** (blocking persona hard-fails, post-cutoff fact-check mandate, a Norwegian-chronicle `voice-scrubber`, render+annotate operator gates, STATE.md-reconciled edition state).

+- **Editorial-review craft gate BEFORE the persona sweep (v2.4)** — Step 5.5 runs the new `editorial-reviewer` (Opus) on the fact-checked draft, two axes (prosa-håndverk + narrativ-arkitektur), ≤10 flags severity-ranked BLOCK/REWORK/NICE, surfaced to the operator via `SendUserFile`. It runs *before* the persona sweep so the personas measure resonance instead of stumbling on craft noise; `persona-reviewer` is unchanged (one measures craft, one measures response). Mirrors Maskinrommet §C2.
 - **Visual-assets gate BEFORE lock (v2.3)** — Step 7.5 decides image needs from the article type (method-heavy → 1–2 inline figures; diagnosis-heavy → cover only), briefs each image, generates via mcp-image or an external `cover-raw.png`, surfaces candidates with `SendUserFile`, and copies the approved one to the fixed `cover.png` name. Explicit `format: "carousel"` branch reusing `build-carousel.mjs`.
 - **Blocking persona hard-fails (v2.2)** — `persona-reviewer` + `personas.template.md` make primær «mistet meg», doesn't-own-the-action, sjargong-mur, and modell-/navne-katalog BLOCK-level rewrites, not annotations. The bar is the primær reader's *clean* JA.
 - **Fact-check orthogonal to polish (v2.2)** — `fact-checker` web-searches every post-cutoff claim (never confirms from memory) and runs an explicit checklist for person titles, org-varying "standards", over-credited studies, source scope, and founding/release years.
