chore: trigger ci

Adds the M5.2 surface set per PLATFORM_ARCHITECTURE.md §5a. Every route
is a navigable skeleton with a per-route empty-state pointing at the
milestone that ships the real content; the Nav component filters links
by session.org_roles so an IT_ADMIN sees settings + api-keys, a CXO
sees billing, a USER sees only dashboard + products + support, etc.

New surfaces (10):
  /[slug]/products              M10.1
  /[slug]/projects              M10.1
  /[slug]/catalog               M11.1
  /[slug]/settings              M10.1
  /[slug]/settings/users        M10.1
  /[slug]/settings/api-keys     M15.1
  /[slug]/settings/integrations M15.2
  /[slug]/billing               M8.3
  /[slug]/audit                 M10.2
  /[slug]/support               M9.1

Dashboard upgraded: reads session.products, renders one tile per
entitled product (real tile content lands in M10.1). Empty-state when
the user has no entitlements yet — links into the catalog flow.

Backstage stub at /__backstage__ — middleware already rewrites
backstage.<apex>/* to this prefix; real RBAC against BREAKPILOT_ADMIN /
SUPPORT_ENGINEER / SALES_REP lands in M13.2.

Layout enforces tenant-slug match: a session with tenant_slug=A trying
to view /B/... gets redirected to /A/dashboard. Prevents JWT-replay
across tenants (defence in depth; the real guard is at the API layer,
which M4.3 adds in tenant-registry).

src/lib/session.ts is the single source of truth for the role matrix
+ canSee(surface) helper. 13 vitest cases, 100% coverage of src/lib.

 ### Added
+- feat(app): M5.2 — customer-area route shells (settings, billing, audit, support, catalog, products, projects, settings/{users,api-keys,integrations}); shared Nav component reads session.org_roles and shows only what each role can see; backstage stub at /__backstage__; dashboard renders product tiles from session.products
+- chore(deps): bump next + eslint-config-next to 16.2.6 to clear trivy CVEs (CVE-2025-29927 critical + 7 highs in next 15.0.3)
+- feat(app): Next.js 16 + Auth.js v5 skeleton with host→slug middleware, tenant context layout, OIDC sign-in flow

+## Architecture notes
+
+- **Host → slug routing**: `src/middleware.ts` parses `Host` header via `parseHost()` (in `src/lib/host.ts`) and rewrites the request path to `/<slug>/...`. URL bar stays unchanged. Apex hosts and unknown subdomains fall through unmodified.
+- **Tenant context**: `src/app/[slug]/layout.tsx` fetches the tenant from `tenant-registry` (`src/lib/tenant-registry.ts`). 404 → `notFound()`; HTTP errors bubble up.
+- **Auth**: `src/auth.ts` is the Auth.js v5 config — Keycloak provider, tenant-context claims (`tenant_id`, `tenant_slug`, `org_roles`, `products`, `plan`, `tenant_status`) propagated via JWT/session callbacks. Real RBAC enforcement lands in M5.2 / M10.1.
