feat(ms-ai-architect): release v1.10.0 — felles grunnskjelett + Tier 3-adopsjon

Playground v3 internal refactor with shared visual signature across all 17
report renderers. Plugin contract (24 commands, 12 agents, 5 skills, 2 hooks,
MCP) is unchanged — release is playground-internal.

- Foundation helpers: renderPageShell, renderVerdictPill, renderKeyStatsGrid,
  inferVerdict, inferKeyStats, KEY_STATS_CONFIG
- Schema v1->v2 migration (idempotent via dataVersion=2 guard)
- Tier 3 supplement components integrated in 11 renderer slots
- Parser extensions: parsePhasedPlan (status/currentPhaseIndex/pocVerdict),
  parseComparison (winner), parseMatrixRisk (_consumer-strategi A)
- Onboarding redesign: 4 strukturerte / 14 fritekst
- Light-theme tokens (Aksel-aligned, WCAG 2.2 AA)
- Validation: 201 statisk + 70 parser + 7 migrasjon = 278 PASS

A11Y-RAPPORT.md populated with code-based static assessment of all 4 surfaces
and 17 renderers. Browser-axe-core run still pending per MANUAL-CHECKLIST.md
section 10.

Docs updated per OBLIGATORISK three-level rule:
- plugin README.md, plugin CLAUDE.md, marketplace root README.md, CHANGELOG.md
