Check who on an Attio deal can be emailed in Constant Contact

**Objective:** For the Attio deal named {deal-name}, report whether each associated person is reachable by Constant Contact email, and how they have engaged with campaigns in the last {lookback-days} days (default 90).

**Step 1: Find the deal in Attio**

Call `attio-get-record-deals` (Attio server) with `deal-name.contains` set to {deal-name}. If more than one deal matches, list them with stage, value and owner and stop. If none match, say so and stop.

**Step 2: Get the people on the deal**

Read the associated people from the deal. For each one, call `attio-get-record-people` with the person's record id as `record-id` if the deal gives ids, otherwise with `name` set to the person's name. Collect each person's name, job title and email addresses. If a person has no email address, mark them "no email in Attio" and skip Step 3 for them.

**Step 3: Check each person in Constant Contact**

For every email address, call `constant-contact-get-contact` (Constant Contact server) with `email-address` set to it. Then for each contact found, call `constant-contact-get-contact-activity` with the contact id as `contact-id` and a `created-date.from` of {lookback-days} days ago. Try each of a person's addresses before calling them missing.

**Step 4: Report**

A table with one row per person: name, role, Attio email, in Constant Contact (yes or no), permission to send, number of campaign interactions in the period, last interaction date. Under it, a one-line verdict for the deal: how many of its people can be emailed and how many have engaged.

**Rules & Guidelines:**

* Attio tools are on the Attio server; Constant Contact tools are on the Constant Contact server.
* Read-only. Do not call `attio-add-company`, `attio-update-company`, `attio-upsert-company`, `attio-delete-company`, `attio-add-person`, `attio-update-person`, `attio-upsert-person`, `attio-delete-person`, `attio-add-deal`, `attio-update-deal` and `attio-delete-deal`, or `constant-contact-add-contact`, `constant-contact-update-contact`, `constant-contact-add-contact-note`, `constant-contact-add-contact-tag`, `constant-contact-update-contact-tag`, `constant-contact-add-contact-list`, `constant-contact-update-contact-list`, `constant-contact-add-campaign`, `constant-contact-update-campaign` and `constant-contact-resend-campaign-to-non-openers`.

**Validation:**

* A contact whose permission to send is not granted is "not emailable", even if present.
* If the deal has no associated people, say so and stop.
