See a customer's whole AvaTax tax profile in one answer

**Objective:** Build a tax profile of the AvaTax customer matching `{customer}` (a customer code or part of the name), for `{company}` if given.

**Step 1: Find the customer**

Call `avalara-avatax-get-customer` with `customer-code` = `{customer}`. If nothing matches, call it again with `name.contains` = `{customer}`. If more than one customer matches, list them (customer-code, name, city, region) and stop.

**Step 2: Read recent transactions**

Call `avalara-avatax-get-transaction` with `customer-code` set to the chosen customer code (and `company`). Summarise count, total-amount, total-tax, total-exempt, and the latest `date` and `status` values.

**Step 3: Read certificates**

Call `avalara-avatax-get-certificate` (with `company`). Certificates are not filterable by customer, so match on the customer's region, country and exposure-zone-name only as a hint and say it is an inference.

**Step 4: Report**

Give the customer details (code, name, address, taxpayer-id-number present or not, last-transaction), the transaction summary, exempt versus taxed share, and a list of concerns: no taxpayer ID, no recent activity, exempt sales with no matching certificate, uncommitted transactions.

**Validation:**

* If no customer matches, say so and stop.

**Rules & Guidelines:**

* This prompt is read-only. Call only the `avalara-avatax-get-*` tools named above. Never call any avalara-avatax tool that adds, updates, deletes, commits, uncommits, voids, unvoids, adjusts, refunds, locks, settles or creates anything.
* Report what the data shows. Do not guess values the tools did not return, and say so when a field came back empty.
* Use `max-records` to keep each read small, and say when a result may be truncated by it.
