Check NetSuite invoice lines against Avalara AvaTax

**Objective:** For NetSuite invoice `{invoice-number}`, compare its lines with the AvaTax transaction lines and show which lines were taxed and under which tax code.

**Step 1: Read the invoice lines**

Call `netsuite-get-invoiceitem` with `document-number` = `{invoice-number}`. If nothing returns, stop and say no lines were found. Keep `item`, `item-description` and `rate` for each line.

**Step 2: Find the AvaTax transaction and its lines**

Call `avalara-avatax-get-transaction` with `code` = `{invoice-number}` and `company` = `{company}`. If nothing returns, report the invoice as not in AvaTax and stop. Take the transaction `id` and call `avalara-avatax-get-transaction-line` with `transaction-id` set to it.

**Step 3: Match lines**

Match each NetSuite line to an AvaTax line by `item` against `item-code`. For lines with no match, fall back to `description`. For each matched line, call `avalara-avatax-get-item` with `item-code` to read its `tax-code`; skip this call if the item was already looked up.

**Step 4: Report**

Table per line: item, NetSuite rate, AvaTax `line-amount`, `taxable-amount`, `exempt-amount`, `tax`, `tax-code`, and a flag. Flag lines with no AvaTax counterpart, lines with zero tax, lines with a blank `tax-code`, and lines where `exempt-amount` is not zero.

**Rules & Guidelines:**

* Tools starting with netsuite-get are on the netsuite MCP server. Tools starting with avalara-avatax-get are on the avalara-avatax MCP server. Both servers must be connected.
* This prompt is read-only. Call only the get tools named above. Never call any avalara-avatax Action tool (for example `avalara-avatax-transaction-create`, `avalara-avatax-transaction-adjust`, `avalara-avatax-transaction-void` or `avalara-avatax-transaction-commit`), and never create or change anything in NetSuite.
* If `{company}` is empty, omit the `company` parameter on AvaTax calls.

**Validation:**

* If line counts differ between the systems, say so before the table.
* Item names in NetSuite may include a parent prefix; match on the text after the last colon if the exact name finds nothing.
