Answer customer account questions across WooCommerce and Intacct

**Objective:** Give a single view of the customer with email `{customer-email}` across WooCommerce and Intacct, covering the last `{lookback-days}` days (default 90).

**Step 1: Read WooCommerce**

Call `woocommerce-get-customer` with `email` = `{customer-email}` and keep the name, `billing-company`, `billing-city`, `billing-state`, `created-date` and `paying-customer`.

Call `woocommerce-get-order` with `customer-email` = `{customer-email}` and `created-date.from` = today minus `{lookback-days}` days (default 90). Call `woocommerce-get-refund` with `customer-email` = `{customer-email}` over the same range.

**Step 2: Find the Intacct customer**

Try, in order, and stop at the first single match:

1. `intacct-get-contact` with `email` = the WooCommerce email, then `intacct-get-customer` with `customer-name` = the contact's `company-name`.
2. If the WooCommerce customer has a `billing-company` (from `woocommerce-get-customer`), `intacct-get-customer` with `customer-name` = that company.
3. `intacct-get-customer` with `customer-name` = the WooCommerce first and last name.

Treat a match as confirmed when the Intacct customer's `email` equals the WooCommerce email (ignoring case) or is empty. If it holds a different email, report it as a possible wrong match instead of using it.

If there is no match, report the WooCommerce side only, say the customer is not in Intacct, and suggest the sync-customer-to-intacct prompt.

**Step 3: Read Intacct**

Call `intacct-get-customer` with `customer-id` and keep `status`, `term`, `credit-limit`, `total-due` and `last-invoice-date`.

Call `intacct-get-invoice` with `customer-id` and `total-due.min` = 0.01 for open invoices; mark as overdue those whose `due-date` is before today.

Call `intacct-get-ar-payment` with `customer-id` and `receipt-date.from` = the start of the range.

**Step 4: Report**

* Identity: the name, company, city and state on each side, flagging any that disagree.
* Store activity: order count, order total, refund total, last order date, and orders by status.
* Ledger position: total due, credit limit and headroom, term, open and overdue invoices with amounts and days overdue, payments received in the range.
* Gaps: WooCommerce orders in the range that are not processing, completed or refunded, and completed orders with no Intacct invoice whose `reference-number` equals the order number (check against invoices read with `intacct-get-invoice` for this customer over the range).

**Rules & Guidelines:**

* `woocommerce-get-customer`, `woocommerce-get-order` and `woocommerce-get-refund` are on the woocommerce server. `intacct-get-contact`, `intacct-get-customer`, `intacct-get-invoice` and `intacct-get-ar-payment` are on the intacct server.
* This prompt is read-only. Do NOT call `woocommerce-update-customer`, `woocommerce-update-order`, `intacct-update-customer`, `intacct-create-customer` or any other write tool.

**Validation:**

* If WooCommerce has no customer or order for the email, check Intacct anyway and say the email is unknown to the store.
* If Intacct amounts are in a different currency from the store orders, show both currencies and do not add them together.
