docs(linkedin-studio): repo-standard BADGE-COUNT — 7 → 5 badges (behold katalog-speilede akser)

Fjerner platform- og reference_docs-badgene. De tre stat-badgene katalogens
check-versions.mjs speiler per akse (commands/agents/hooks) beholdes, sammen med
version (intern konsistenssjekk mot plugin.json) og license.

README-H1-funnet er vurdert som bevisst: menneskelesbar tittel er husmønsteret
på tvers av marketplace-repoene.

 Most experts know they *should* post on LinkedIn — and quietly don't. The blank editor wins. LinkedIn Studio turns that chore into a system: structured workflows that take you from idea to published, in your own voice, calibrated to how LinkedIn's **topic-relevance** ranking model (2026) actually distributes content. Two engines under one surface — a **feed engine** for short-form posts, carousels, and video scripts, and a **long-form engine** that runs newsletter editions and essays through a serious editorial pipeline before they ever lock.
