docs(linkedin-studio): N4 sannhetspass — GR-modellkorreksjon + maturity/saves/kø/SB-header + refs-badge 28

Del 1 (RE-verifisert mot ground truth): README maturity-note (herding 29/29 +
kald-review 29/29; gjenstår = GUI), CLAUDE.md maturity-linje (B-F10),
hardening-plan-køen t.o.m. S31a/b/c, second-brain-header (SB-S3a-e landet,
kun S4 gjenstår).

Del 2: D-1 BLOCKER — algorithm-signals GR-seksjonen omskrevet mot primærkilde
(LinkedIn engineering-blogg 2026-03-12, Hristo Danchev: Generative Recommender
(GR) offisielt navn + LLM-retrieval + utrulling annonsert); fabrikasjonsflagget
avviste en ekte primærkilde og er trukket med korreksjonsnote; 360Brew-skepsis
beholdt. D-2 — saves-begrunnelse: Marketing API v202604 har POST_SAVE på
/memberCreatorPostAnalytics (partner-gated; manuell inntasting forblir riktig
UX). B-F11 — README refs-badge 26->28 + 25-document->28-document (ls
references/*.md = 28). CLAUDE.md Architecture faar specifics-bank +
contract-gate-linjer.

CHANGELOG-catchup kommer i release-committen (0.6.0) for aa holde
versjonsdeklarasjonene konsistente per commit.
