See a customer's BigCommerce orders and Capsule CRM activity

**Objective:** For the customer with email `{email}`, show their BigCommerce orders from the last `{lookback-days}` days (default 90) together with what Capsule CRM holds: opportunities, cases and open tasks.

**Step 1: Orders in BigCommerce**

Call `bigcommerce-get-customer` with `email` = `{email}`. If none or several match, say so and stop. Then call `bigcommerce-get-order` with `customer-id` = the customer `id` and `date-created.from` = today minus `{lookback-days}` days. Keep `id`, `date-created`, `status`, `payment-status`, `total-including-tax`, `refunded-amount`.

**Step 2: Contact in Capsule CRM**

Call `capsule-crm-get-party` with `email` = `{email}`. If none match, show the orders and report the customer as absent from Capsule CRM. If several match, list them and stop. Keep `party-id`, `name`, `owner-name`, `last-contacted-date`.

**Step 3: Capsule CRM context**

Using the contact: call `capsule-crm-get-opportunity` with `party-name.contains` = the contact `name`; call `capsule-crm-get-case` with `party-name` = the contact `name`; call `capsule-crm-get-task` with `party-id` = the `party-id` and `status` = OPEN. If a status value is rejected, call without it and filter by hand.

**Step 4: Report**

Give the customer header (name, company, owner, last contacted), then three sections: orders (table with totals and refunds), opportunities (name, milestone-name, value, expected-close-date, owner-name), and cases and open tasks (name or description, status, due-date). End with two sentences on what the sales or support owner should do next, for example an order with a refund and no open task.

**Rules & Guidelines:**

* Tools whose names start with bigcommerce-  are on the bigcommerce server; tools whose names start with capsule-crm-  are on the capsule-crm server. Both must be connected.
* Read-only: do not call any add, update or delete tool on either server (for example `bigcommerce-customer-update` or `capsule-crm-add-note`).
* Customers are matched across the two systems by email address, compared case-insensitively.

**Validation:**

* If `{lookback-days}` is empty, use 90.
* If a name filter in Capsule CRM could match other contacts, keep only rows whose party-name equals the contact name.
* Report empty sections as "none found".
