Initial commit — @crema/integration-registry-client

Typed client + types for the arcadia integration registry (on arcadia-llm-gateway).
One createIntegrationsApi(client, mode) factory serves both surfaces:
- operator → /api/v1/integrations* (any scope, scope filters)
- tenant   → /api/v1/me/integrations* (scope forced server-side)

Plus shared types (Integration/Credential/UsageEntry/*Input/TestVerdict) and
display helpers (formatUsd, credentialHealth). Consumed by arcadia-admin and
arcadia-console as a sibling lib via vite/tsconfig aliases (no build step).
Secrets are write-only; the rich panels stay per-app.

+# @crema/integration-registry-client
+
+Typed client + types for the **arcadia integration registry** — the external-API
+credential plane hosted on `arcadia-llm-gateway`. Consumed by `arcadia-admin`
+(operator) and `arcadia-console` (tenant) as a sibling lib via vite/tsconfig
+aliases (no build step — the app compiles `src/` directly).
+
+```ts
+import { createIntegrationsApi } from "@crema/integration-registry-client"
+
+// gateway-pointed ArcadiaClient (see each app's app/lib/gateway.ts)
+const api = createIntegrationsApi(gatewayClient, "tenant") // or "operator"
+
+await api.list()
+await api.create({ provider: "tavily", capability: "web_search" })
+await api.test(id) // throws ArcadiaError on 409 expired / 429 over-budget
+```
+
+- `operator` mode → `/api/v1/integrations*` (any scope, scope filters honoured).
+- `tenant` mode → `/api/v1/me/integrations*` (scope forced to the caller server-side).
+
+Secrets are **write-only**: reads carry `has_secret`, never a value.
+
+The rich management **page/components stay per-app** (they use each app's shadcn
+primitives and the operator/tenant surfaces legitimately diverge) — this lib owns
+the client, types, and display helpers only.
