Match Shopify B2B companies to Rillet customers, rule by rule

**Objective:** Match every Shopify B2B company (or only `{company-name}` if given) to a Rillet customer and report which companies exist in only one system and which disagree on name or contact email.

**Step 1: Read the Shopify companies**

Call `shopify-get-company`, filtered by name.contains `{company-name}` if given. Note company-id, name, external-id, orders-count and total-spent. Then call `shopify-get-company-contact` for each company-id and note customer-email and is-main-contact.

**Step 2: Read the Rillet customers**

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

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

1. Shopify external-id equals a Rillet customer-id: exact match.
2. Shopify name equals Rillet name or invoicing-name, ignoring case and punctuation: exact match.
3. Names equal after dropping legal suffixes (Inc, LLC, Ltd, Corp, Co): probable match.
4. A Shopify contact email equals a Rillet customer email: probable match.

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

**Step 4: Report**

A summary line, then these tables:

1. Matched: Shopify name, Rillet name, rule used.
2. Probable: same, plus what differs. Say these need a person to confirm.
3. In Shopify only: name, orders-count, total-spent, main contact email.
4. In Rillet only: name, customer-id, emails. Include these only when no `{company-name}` was given. Many Rillet customers never buy through Shopify, so say this list is for information.
5. Email disagreements: matched companies whose Shopify main contact email is not among the Rillet customer's emails.

Recommend setting the Shopify external-id to the Rillet customer-id for every probable match, so future runs match exactly.

**Rules & Guidelines:**

* `shopify-get-company` and `shopify-get-company-contact` are on the shopify 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`, `shopify-update-company` or `shopify-update-company-contact`. Shopify has no street address or zip for a company, which `rillet-add-customer` requires, so creating the missing customers is not something to attempt from here.

**Validation:**

* If Shopify returns no companies, say the store has no B2B companies and stop.
* If Rillet returns no customers, report every company as in Shopify only.
