Rank NetSuite campaigns by profit, not by feel

**Objective:** Review campaigns starting from {start-from} (default 180 days ago), optionally with total cost of at most {max-cost}.

**Step 1: Campaigns**

Call `netsuite-get-campaign` with `start-date.from` and, if given, `total-cost.max`. Note `total-cost`, `revenue`, `profit`, `projected-income` and `number-of-purchasers`.

**Step 2: Leads**

Call `netsuite-get-lead` and `netsuite-get-prospect` with no filter other than the row limit, and count those whose `date-created` falls within each campaign's dates.

**Step 3: Report**

A table ranked by profit with cost, revenue, return on cost (revenue divided by cost), purchasers and leads created in window. Highlight campaigns that lost money and those that exceeded projected income. State that lead counts are by date window only, not true attribution.

**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.
