Find NetSuite sales orders stuck before shipping or billing

**Objective:** Find sales orders dated between {date-from} and {date-to} (default last 60 days to today), optionally for one {customer}, that have no fulfillment or no invoice.

**Step 1: Orders**

Call `netsuite-get-salesorder` with `date.from`, `date.to` and, if given, `customer`. Note `document-number`, `status`, `total` and `customer-id`.

**Step 2: Downstream documents**

Call `netsuite-get-itemfulfillment` and `netsuite-get-invoice` with `date.from` set to {date-from}, `date.to` set to today, and the same customer. Use `netsuite-get-transactionlink` with `from-document` set to an order number to confirm a link when a match is unclear.

**Step 3: Report**

Two lists: orders with no fulfillment, and fulfilled orders with no invoice. Show document number, customer, date, status, total and days waiting. Sort by days waiting. Finish with counts and the value held up.

**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.
