Know which online buyers are set up in Rillet

**Objective:** Match every paying WooCommerce customer (or only those whose email contains `{email-contains}`, if given) to a Rillet customer, and report which customers exist in only one system and which disagree on name or location.

**Step 1: Read the WooCommerce customers**

Call `woocommerce-get-customer` with paying-customer set to true, and email.contains `{email-contains}` if it was given. Note customer-id, email, first-name, last-name, billing-company, billing-city, billing-state, billing-country and created-date.

**Step 2: Read the Rillet customers**

Call `rillet-get-customers` and `rillet-get-customer-emails`. Neither takes filters. Note customer-id, name, invoicing-name, city, state, country, and each customer's emails.

**Step 3: Match, in this order**

1. The WooCommerce email equals a Rillet customer email, ignoring case: exact match.
2. The WooCommerce billing-company equals the Rillet name or invoicing-name, ignoring case and punctuation: probable match.
3. The WooCommerce first-name and last-name together equal the Rillet name or invoicing-name, ignoring case: probable match.

Stop at the first rule that matches. If a rule matches more than one Rillet customer, list the customer as ambiguous with all candidates.

**Step 4: Report**

A summary line, then these tables:

1. Matched by email: WooCommerce email, Rillet name.
2. Probable: WooCommerce name, company and email, Rillet name, rule used. Say these need a person to confirm, and that adding the WooCommerce email to the Rillet customer would make future runs match exactly.
3. In WooCommerce only: email, name, company, billing-country, created-date.
4. In Rillet only: name, customer-id, emails. Include these only when no `{email-contains}` was given. Many Rillet customers never buy online, so say this list is for information.
5. Location disagreements: matched customers whose billing-country or billing-state differs from the Rillet country or state.

**Rules & Guidelines:**

* `woocommerce-get-customer` is on the woocommerce server. `rillet-get-customers` and `rillet-get-customer-emails` are on the rillet server.
* This prompt is read-only. Do not call `rillet-add-customer`, `rillet-update-customer`, `woocommerce-add-customer` or `woocommerce-update-customer`. WooCommerce does not return a street address, which `rillet-add-customer` requires, so creating the missing customers is not something to attempt from here.
* Guest checkouts have no WooCommerce customer record and will not appear. Say so if the user asks why an order's buyer is missing.

**Validation:**

* If WooCommerce returns no paying customers, say so and stop.
* If Rillet returns no customers, report every WooCommerce customer as in WooCommerce only.
