feat(llm-security): playground v7.6.0 — Tier 3 referanse-case komplett

Komplett integrasjon av playground-design-system Tier 3-komponenter
i playground-en. Playground er nå referanse-case for hva DS-en kan
levere når alle komponenter brukes som tilsiktet. Levert over 5 sesjoner
med atomic commits per sesjon.

Endringer i v7.6.0 (fase 1-7):
- Fjernet ~30 duplikat-CSS-deklarasjoner (DS vinner cascade)
- Page-shell harmonisert (page__header-klynge på alle 4 overflater)
- Scope-identitet via badge--scope-security
- verdict-pill-lg erstatter custom verdict-pill
- Onboarding wizard via Tier 3 form-progress + fp-step
- Tier 3 spesialkomponenter integrert:
  - tfa-flow + tfa-leg + tfa-arrow (toxic-flow-rapport)
  - mat-ladder + mat-step (posture-modenhet)
  - suppressed-group (narrative-audit)
  - codepoint-reveal + cp-tag/cp-zw/cp-bidi (UNI-funn)
  - top-risks + top-risk[data-severity] (rangert funn-listing)
  - recommendation-card[data-severity] (clean/harden/audit/posture/
    pre-deploy/plugin-audit advisory)
  - risk-meter (band-visualisering 0-100 på 5 archetypes)
  - card--severity-{level} (findings-cards modifier)

5 nye DS-helpers + mapSeverityToCardLevel + parseNarrativeAudit.
renderRecommendationsList utvidet med severity-param. renderHarden-rewrite
fra diff-row-struktur til recommendation-card med action-mapping.

Ingen scanner/hook-atferd berørt. Kun visuelt og strukturelt.
A11Y-rapport oppdatert (WCAG 2.1 AA bekreftet, severity-soft fargepar
verifisert, semantiske elementer erstatter generic div).

Versjon bumpet v7.5.0 → v7.6.0:
- plugins/llm-security/.claude-plugin/plugin.json
- plugins/llm-security/package.json
- plugins/llm-security/README.md (badge + Playground-seksjon + history)
- plugins/llm-security/CLAUDE.md (header + ny v7.6.0-blurb)
- plugins/llm-security/CHANGELOG.md ([7.6.0] entry)
- README.md (rot — llm-security-rad + history-bullet)
- plugins/llm-security/playground/llm-security-playground.html (footer)

Filendring playground.html totalt over 5 sesjoner: 10209 → 10677 linjer
(+468 netto). Per-sesjons-commits: 9ef0c48 (Sesjon 1, fase 1-2),
2481133 (Sesjon 2, fase 3-4), fbda041 (Sesjon 3, fase 5a-d),
e9e5cee (Sesjon 4, fase 5e-h).

Verifisering bekreftet:
- 18/18 renderere passerer regresjons-smoke-test mot dft-komplett-demo
- Grep-criteria oppfylt: top-risks 5, recommendation-card 32,
  risk-meter 7 (5 archetypes), card--severity- 4, verdict-pill-lg 20,
  fp-step 12, badge--scope-security 5, tfa-flow 3, mat-ladder 2,
  suppressed-group 8, codepoint-reveal 12
- Window-globaler intakt, JS parse OK, demo-state JSON parse OK

Kjent begrensning: parsed.findings er tom for deep-scan/audit demo-
fixturer (parser-begrensning, defensiv design — dokumentert i CHANGELOG
+ A11Y-rapport, sporet for v7.6.x patch).

Parsere + renderere for alle 18 produces_report-kommandoer, 18 markdown test-fixtures som kontrakt-anker, komplett demo-prosjekt med alle 18 rapporter ferdig parsed, vendor-synket design-system, 9 Playwright-genererte screenshots. 11 nye `window`-globaler eksponert for testing/automasjon (`__store`, `__navigate`, `__loadDemoState`, `__PARSERS`, `__RENDERERS` …).

 - **v8.0.0 env-var deprecation runway (D3, v7.3.0)** — Hook configuration has historically been split between process env-vars and the team-distributable `.llm-security/policy.json` file. Until v7.3.0 the two surfaces could disagree silently. The new `getPolicyValueWithEnvWarn()` helper in `scanners/lib/policy-loader.mjs` now emits a one-time-per-process stderr line whenever both surfaces are explicitly set:
