See which NetSuite purchase orders have not been received

**Objective:** Find purchase orders dated from {date-from} (default 90 days ago) that have not been fully received, optionally for one {vendor}.

**Step 1: Orders**

Call `netsuite-get-purchaseorder` with `date.from` and, if given, `vendor`. Then call `netsuite-get-purchaseorderitem` with `vendor-company-name` set to the vendor (when one was given) for the line quantities.

**Step 2: Receipts**

Call `netsuite-get-itemreceipt` and `netsuite-get-itemreceiptitem` with `date.from` and the vendor, and compare to the orders by `document-number` and item. Use `netsuite-get-transactionlink` with `from-document` set to the purchase order number if the match is not clear.

**Step 3: Report**

A table of purchase order, vendor, date, item, ordered quantity, and whether a receipt was found. List orders with no receipt first, oldest first. State clearly where you could only match at header level because line data lacked a quantity received.

**Rules & Guidelines:**

* This is a read-only job. Do not call any tool whose name starts with netsuite-add- or netsuite-update-, and never change, create or delete a record.
* Report only what the tools return. Do not estimate or invent figures; if a total is needed, add up the rows you actually retrieved and say so.
* If a read returns the maximum number of rows, say the result may be truncated and suggest narrowing the filters.
* Dates are YYYY-MM-DD. Where an input is blank, use the default stated in the Objective.

**Validation:**

* If a read returns nothing, say so and stop rather than guessing.
* If an input is ambiguous, list the candidates and ask which one is meant.
