See which customers Constant Contact covers and misses

**Objective:** Compare Dynamics SL customers against Constant Contact contacts and report which customers are missing from Constant Contact, which cannot be emailed, and where names or phone numbers disagree. Limit the customers to state `{state}` and salesperson `{salesperson-id}` when given (both optional; default all active customers, up to 200).

**Step 1: List the customers in Dynamics SL**

Call `dynamics-sl-get-customers` with `status` set to active, plus `state` = `{state}` and `salesperson-id` = `{salesperson-id}` when provided, and `max-records` 200. Keep `customer-id`, `customer-name`, `email-address`, `phone-number`, `city` and `state` for each.

**Step 2: Look each customer up in Constant Contact by email**

For each customer with a non-blank `email-address`, call `constant-contact-get-contact` with `email-address` set to that value. If the SL field holds several addresses separated by `;` or `,`, try each in turn and use the first that matches. Customers with no email go straight into the "no email in Dynamics SL" group.

**Step 3: Classify**

Put each customer in exactly one group:

* **Missing from Constant Contact** - has an email in SL, no contact found.
* **Not mailable** - contact found but `permission-to-send` is not an opt-in value (unsubscribed, pending, temp hold).
* **Details differ** - contact found and mailable, but the contact's company-name does not match the SL customer name, or the phone numbers differ once punctuation is ignored.
* **Matched** - everything lines up.
* **No email in Dynamics SL**.

**Step 4: Report**

A one-line count per group, then a table per group (skip Matched unless there are fewer than 20): customer id, customer name, SL email, contact id, the differing values side by side.

**Rules & Guidelines:**

* `dynamics-sl-get-customers` is on the dynamics-sl server; `constant-contact-get-contact` is on the constant-contact server.
* This prompt is read-only. Do not call `constant-contact-add-contact`, `constant-contact-update-contact`, `constant-contact-add-contact-note` or any other constant-contact write tool.
* Match on email only, case-insensitive and trimmed. Never match a customer to a contact by name alone.
* If the user has named a Dynamics SL company, pass it as `company` on every dynamics-sl call.

**Validation:**

* If Dynamics SL returns no customers, say so and stop.
* If 200 customers came back, say the list was capped and suggest narrowing by state or salesperson.
* If one email matches more than one contact, list it under Details differ with every contact id.
