feat(integrations): add Zapier integration for Mem0

Zapier Platform CLI app (zapier-mem0) with Add Memory / Delete Memory
creates and Search Memories / Get Memories searches against the Mem0 v3
API. Custom API-key auth (Authorization: Token), base-URL + auth
injected via beforeRequest middleware, non-2xx surfaced as errors.

Add Memory polls GET /v1/event/{id}/ for async extraction. Includes an
E2E test suite via createAppTester.

+# Zapier integration for Mem0
+
+A [Zapier](https://zapier.com) integration for [Mem0](https://mem0.ai) — the memory layer for AI agents. Add, search, list, and delete long-term memories from any Zap.
+
+Built with the [Zapier Platform CLI](https://docs.zapier.com/platform/quickstart/cli-tutorial).
+
+## Actions
+
+| Type | Name | Endpoint |
+| --- | --- | --- |
+| Create | **Add Memory** | `POST /v3/memories/add/` |
+| Create | **Delete Memory** | `DELETE /v1/memories/{id}/` |
+| Search | **Search Memories** | `POST /v3/memories/search/` |
+| Search | **Get Memories** | `POST /v3/memories/` |
+
+**Add Memory** runs LLM extraction asynchronously by default; the action polls the event until it completes and returns the resulting memories. Turn off **Wait for Completion** to return immediately, or set **Infer = false** to store verbatim (synchronous).
+
+## Authentication
+
+Custom (API key) auth. Provide a Mem0 API key from [app.mem0.ai](https://app.mem0.ai) → Settings → API Keys. It is sent as `Authorization: Token <key>`.
+
+## Development
+
+```bash
+npm install
+MEM0_API_KEY=m0-... npm test   # runs the E2E suite against api.mem0.ai
+```
+
+To deploy (maintainers): `zapier login && zapier push`.
