Find 2Checkout leads that are not in your Mailchimp audience

**Objective:** List 2Checkout leads that have no matching member in Mailchimp audience `{list-name}`, looking at up to `{max-leads}` leads (default 25).

**Step 1: Read the leads**

Call `2checkout-get-lead` with `max-records` set to `{max-leads}`. Take `lead-code`, `billing-email`, `billing-first-name`, `billing-last-name` and `billing-country-code`. Skip rows with no billing-email and count them.

**Step 2: Check Mailchimp**

For each lead call `mailchimp-get-list-member` with `email` set to `billing-email` and `list-name` set to `{list-name}`. A row means the lead is present; record its status.

**Step 3: Report**

Table of leads with no member row: lead-code, email, name, country. Then a short list of leads present but not subscribed, with their status. End with counts: checked, present, missing, skipped for no email.

**Rules & Guidelines:**

* `2checkout-*` tools belong to the 2checkout server and `mailchimp-*` tools to the mailchimp server; both servers must be connected.
* This prompt is read-only. Never call any 2checkout write tool (for example `2checkout-customer-add`, `2checkout-customer-update`, `2checkout-subscription-disable`) or any mailchimp write tool (`mailchimp-add-list-member`, `mailchimp-update-list-member`, `mailchimp-add-segment-member`).
* Match emails case-insensitively after trimming spaces; never alter the stored value in the report.

**Validation:**

* If `{list-name}` matches no audience, say so and stop.
* If 2Checkout returns no leads, say so and stop.
