Find Intacct invoices that never reached AvaTax

**Objective:** Find Intacct invoices for company {company} dated {date-from} to {date-to} that have no matching AvaTax transaction, so unreported sales can be fixed.

**Step 1: List invoices in Intacct**

Call `intacct-get-invoice` with `company` = {company}, `invoice-date.from` = {date-from} and `invoice-date.to` = {date-to}. Keep `invoice-number`, `customer-id`, `invoice-date` and `total-amount`.

**Step 2: List transactions in AvaTax**

Call `avalara-avatax-get-transaction` with `company` = {company}, `date.from` = {date-from} and `date.to` = {date-to}. Index the results by `code`.

**Step 3: Match**

Match each invoice's `invoice-number` to an AvaTax `code`. Invoices with no match are the findings. Also list AvaTax sales transactions with no invoice as a secondary finding.

**Step 4: Report**

List each missing invoice with number, customer, date and amount, sorted by amount descending, with counts and total value missing.

**Rules & Guidelines:**

* Tools whose names start with avalara-avatax are on the avalara-avatax server; tools whose names start with intacct are on the intacct server. Both servers must be connected.
* This prompt is read-only. Never call any Intacct create or update tool, and never call any AvaTax action tool (transaction, commit, change or delete tools).

**Validation:**

* If either side returns no records for the range, say so and stop rather than reporting everything missing.
* If a side hits `max-records`, say the check may be incomplete and suggest a narrower range.
* Dates are in YYYY-MM-DD.
