See which new BigCommerce customers have placed an order

**Objective:** Review customers created in the last `{lookback-days}` days (default 30), optionally in customer group `{group-name}`.

**Step 1: Resolve the group (optional)**

If a group name was given, call `bigcommerce-get-customer-group` with `name`; use its `id` as `customer-group-id`. If it does not match exactly one group, list the candidates and stop.

**Step 2: Pull customers**

Call `bigcommerce-get-customer` with `date-created.from` set to the lookback start and `customer-group-id` if resolved.

**Step 3: Check first orders**

For up to 30 customers, call `bigcommerce-get-order` with `customer-id` and count orders.

**Step 4: Report**

New customers per group, the share who have ordered, and a list of those with no orders yet (name, email, company, date created). Mention only business contact fields.

**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.

**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.
