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.

-Full-spectrum LinkedIn content engine — short-form feed posts, carousels, video scripts, and long-form newsletter editions — with the January 2026 360Brew algorithm baked in. v2.0.0 consolidated the surface (27 commands → 24, 16 agents → 14) while adding the long-form `/linkedin:newsletter` orchestrator + two longform-quality gate agents (`fact-checker`, `persona-reviewer`). v2.1.0 added two gates BEFORE prose (Step 2.5 skeleton + Step 3a spine prose) + a third `persona-reviewer` mode (`skjelett`). v2.2.0 hardened the longform gates with the lessons from the second production run (Seres-serien): blocking persona hard-fails, a post-cutoff fact-check mandate, a `voice-scrubber` agent, render+annotate operator gates, and STATE.md-reconciled edition state. **v2.3.0** makes **visual assets an explicit pipeline phase** — new **Step 7.5 (visual-assets)** between annotation (Step 7) and lock (Step 8): cover (+ optional inline figures) or a carousel deck, generated (default `mcp-image`, external `cover-raw.png` accepted) and **operator-gated BEFORE lock** so `render/build-linkedin.mjs` picks up `cover.png` 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. Agents unchanged (15); commands unchanged (24).

Motivated by Del 4: 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. Mirrors the Maskinrommet writing-contract §C2. Pipeline 14 → 15 phases; agents 15 → 16; additive `editorialReview` state. Doc/orchestration-only for the wiring (the new agent + its fasit fixture + lint test are the only new files); commands unchanged (24).
