feat(linkedin-studio): N3 — Step 7.5 kodet-figur-rute + figure-design-guidelines [skip-docs]

MR-F4 S2: (1) commands/newsletter.md Step 7.5 — generate er nå tre ruter;
kodet rute (render/build-figur.mjs) er PRIMÆR for data-figurer
(presisjon/reproduserbarhet), mcp-image beholdes for illustrative,
external uendret. Fasetabell + ressursliste + rute-statuslinje oppdatert.
(2) NY references/figure-design-guidelines.md — designregler (24pt,
fargebudsjett, whitespace), token-konvensjon (profile/brand-tokens.json,
--figur-*, nøytrale defaults), tre render-mål. Refs 27->28.
(3) CLAUDE.md Architecture-linje for rendereren.
scripts/test-runner.sh: EXPECT_REFS 27->28 + fila navngitt i POSTM0_REFS
(named-additions-vakta). Suiter grønne på floor: 138/0 - 140/0 - 35/0 -
53/0 - 245/0 - 134/0.

 - **State updater:** `hooks/scripts/state-updater.mjs` — deterministic state mutations (post tracking, streak, content history pruning). Pure functions, tested, no AI involvement
 - **Clipboard helper:** `hooks/scripts/clipboard-helper.mjs` — cross-platform clipboard (macOS `pbcopy`, Linux `xclip`/`xsel`, WSL `clip.exe`). All content commands auto-copy
 - **iCal generator:** `hooks/scripts/ical-generator.mjs` — RFC 5545 calendar files for batch scheduling. Standalone CLI + importable module
+- **Figure renderer:** `render/build-figur.mjs` — coded data figures (SVG/HTML → PNG via headless Chrome); three targets (article/carousel/single); brand tokens from the user data dir's `profile/brand-tokens.json`, neutral defaults otherwise (see `references/figure-design-guidelines.md`). Standalone CLI + importable module
 - **Post queue:** `assets/drafts/queue.json` (managed by `hooks/scripts/queue-manager.mjs`)
 - **Analytics:** CLI `scripts/analytics/` (TypeScript, needs `tsx` + `npm install`); data `assets/analytics/` (gitignored)
 - **Analytics metrics (S16):** parsed CSV columns + an optional, manually-entered `saves` count (count-only in native LinkedIn analytics since ~Sept 2025, no CSV export / no API). `parseOptionalCount()`: blank / non-numeric / negative → `undefined` (`unknown`, never 0), a genuine `0` is kept; saves surfaced per-post + as `totalSaves`, but **not** folded into `engagementRate`. `dwell` stays **explicitly unmeasurable** (internal to LinkedIn, no export/API). All analytics I/O routes through the `getAnalyticsRoot()` seam (M0 per-user data-dir).
