Show the right BigCommerce order beside a Freshdesk ticket

**Objective:** Give the agent purchase context for Freshdesk ticket `{ticket-id}`, showing up to `{max-orders}` recent orders (default 5).

**Step 1: Read the ticket**

Call `freshdesk-get-tickets` (Freshdesk server) with `ticket-id`. Take `requester-email`, `subject`, `status`, `priority` and `description-text`. If no ticket comes back, stop and say so.

**Step 2: Find the customer**

Call `bigcommerce-get-customer` (BigCommerce server) with `email` set to `requester-email`. If there is no match, call `bigcommerce-get-order` with `billing-email` set to the same address.

**Step 3: Get orders and items**

Call `bigcommerce-get-order` with the `customer-id` (or `billing-email`), up to `{max-orders}` records. For each order call `bigcommerce-get-order-product` with `order-id`. If the ticket text mentions an order number, put that order first.

**Step 4: Report**

Show the ticket summary, then a table of orders (id, date, status, payment-status, total-including-tax, refunded-amount, items shipped) with item names and SKUs. Finish with one sentence on which order the ticket most likely concerns and why.

**Rules & Guidelines:**

* Freshdesk tools: `freshdesk-get-tickets`. BigCommerce tools: `bigcommerce-get-customer`, `bigcommerce-get-order`, `bigcommerce-get-order-product`.
* Do not call any write tool on either server (no freshdesk-add-*, freshdesk-update-*, freshdesk-delete-*, freshdesk-reply-to-ticket, and no bigcommerce-*-add, -update or -delete tools).

**Validation:**

* If the requester has no BigCommerce customer or order, report that plainly; do not invent a match from the name.
* If the ticket has no requester-email, stop and say the join is impossible.
