fix(linkedin-studio): N10 — konfigurerbart målnivå-spenn [skip-docs]

C-8: gjør «praktisk anvendbar på alle nivå» til en konfigurerbar gate-akse og
fjerner den hardkodede primær-personaen. 6-fils scope (KTG-valgt) — gjør
targetLevel til en EKTE ende-til-ende-dimensjon i stedet for et fantomfelt:

- references/longform-quality-rules.md: «non-technical line manager» → brukerens
  konfigurerte target-level span (domene-generelt).
- config/personas.template.md: «primær trumfer» krever nå obligatorisk sekundær i
  MOTSATT ende av spennet; sekundær-NEI kan kun avskrives som «signal, ikke svikt»
  med eksplisitt ceiling-begrunnelse. Ny tekniker-ende-seed (Persona 4,
  Løsningsutvikler/AI-ingeniør) — tidligere kun 3 leder-personas.
- config/edition-state.template.json: additivt articles.NN.targetLevel-slot
  (default null, INGEN schemaVersion-bump — samme mønster som sourceTrendId/language).
- commands/newsletter.md: persister resolvert targetLevel ved Step 1.5-checkpointet.
- agents/persona-reviewer.md: leser articles.NN.targetLevel og plasserer personaene
  på spennet (fallback til persona-ekspertise om feltet er null).

Premiss-korreksjon: planens 4-fils scope antok targetLevel fantes i edition-state
via N7-broen; det stemte ikke (fantes kun i trend-store + fritekst-mapping). +2 filer
(edition-state-slot + newsletter-persist) gjør konsumet reelt.

TDD: ny Section 16q i test-runner (9 UNCOND. .md/.json-greps + non-vacuity self-test);
en vacuity-bug i egen edition-state-check fanget og skjerpet (grep slot-literal
"targetLevel": null, ikke bare ordet — sourceTrendId-docstringen inneholder allerede
"targetLevel"). test-runner 154→163/0, anti-erosion floor 137→146. Øvrige fem suiter
uendret grønne (trends 300 · brain 134 · hooks 140 · tests 35 · render 60).
