Reconcile Rillet and AvaTax tax totals for a period

**Objective:** For invoice dates from `{from-date}` to `{to-date}` (format YYYY-MM-DD), compare the tax Rillet recorded on invoices with the tax AvaTax calculated, and list the invoices that explain any gap. AvaTax company is `{company}` (default: the default company).

**Step 1: Read Rillet invoices**

Call `rillet-get-invoices`. It has no filters, so keep only rows whose invoice-date is in the range. Total the tax-amount and total across them and count them.

**Step 2: Read AvaTax transactions**

Call `avalara-avatax-get-transaction` with `date.from` set to `{from-date}`, `date.to` set to `{to-date}`, `company` if given and a high `max-records`. Keep sales invoices only (document-type SalesInvoice) and exclude those with status Cancelled. Total total-tax and total-amount and count them.

**Step 3: Match**

Match each Rillet invoice to an AvaTax transaction where the AvaTax code equals the Rillet invoice-number. Rows with no match on the other side go into an unmatched list for that side. Among matched pairs, list those where tax-amount and total-tax differ by 0.01 or more.

**Step 4: Report**

Show the two totals and their difference, the counts, then three lists: Rillet invoices with no AvaTax transaction, AvaTax transactions with no Rillet invoice, and matched pairs whose tax differs (invoice-number, Rillet tax, AvaTax tax, difference). Cap each list at 25 rows and say how many more there are.

**Rules & Guidelines:**

* Tools whose names start with avalara-avatax are on the avalara-avatax server; tools whose names start with rillet are on the rillet server. Both servers must be connected.
* This prompt is read-only. Never call any AvaTax action tool (for example `avalara-avatax-transaction-create`, `avalara-avatax-transaction-adjust`, `avalara-avatax-transaction-void`, `avalara-avatax-transaction-commit`) or any Rillet add, update, apply or set tool (for example `rillet-add-invoice`, `rillet-update-invoice`, `rillet-add-credit-memo`).
* Report what the two systems show. Do not present the result as a filed tax return or as tax advice.
**Validation:**

* If the range is empty on both sides, say so and stop.
* If a transaction code does not follow the invoice-number convention, say that matching is unreliable and show totals only.
* If `{from-date}` is after `{to-date}`, stop and ask for a corrected range.
