See a BigCommerce customer's order history in one summary

**Objective:** Show the order history of the customer with email `{customer-email}`, with line items for the most recent `{order-count}` orders (default 5).

**Step 1: Find the customer**

Call `bigcommerce-get-customer` with `email` set to the address. If nothing matches, retry with `email.contains`. If more than one customer matches, list them (id, name, email, company) and stop.

**Step 2: Get the orders**

Call `bigcommerce-get-order` with `customer-id` set to the customer's `id`. If the customer has none, also try `billing-email` with the same address, since guest orders carry no customer id.

**Step 3: Get the items**

For the most recent orders, call `bigcommerce-get-order-product` with `order-id` set to each order id.

**Step 4: Report**

Customer details (name, company, group id, date created), a one-line lifetime summary (order count, total spent, refunds), then each order with status, payment status, total and its items (name, sku, quantity, total).

**Rules & Guidelines:**

* This is a read-only job. Never call any `bigcommerce-*-add`, `bigcommerce-*-update` or `bigcommerce-*-delete` tool. Do not suggest that you changed anything.
* Share only what is needed for the question; do not repeat phone numbers or full addresses unless asked.

**Validation:**

* If a read returns no records, say so plainly and stop; do not invent figures.
* If a result hits the maximum records limit, say the figures may be incomplete and name the filter that would narrow it.
