Show which campaigns reach accounts with live Dynamics 365 pipeline

**Objective:** Show which Dynamics 365 Sales contacts, leads and open opportunities sit behind the people who engaged with the Constant Contact campaign `{campaign-name}`. Engagement means `{engagement-type}`: `clicks` (the default) or `opens`. This is read-only.

**Step 1: Find the campaign in Constant Contact**

Call `constant-contact-get-campaign` with `name` set to `{campaign-name}`. If nothing comes back, retry with `name.contains`. If more than one matches, list them with status and last-sent-date, and stop. Note the campaign's sends, opens and clicks totals.

**Step 2: Collect who engaged**

With the `campaign-id`, call `constant-contact-get-campaign-click` (or `constant-contact-get-campaign-open` when `{engagement-type}` is opens), `max-records` 500. Reduce to unique email addresses, keeping each person's first-name, last-name and, for clicks, the links they clicked.

**Step 3: Match each email in Dynamics 365 Sales**

For each email, call `dynamics-365-sales-get-contacts` with `email`. If that is empty, call `dynamics-365-sales-get-leads` with `email`. If both are empty, the person is "unknown to CRM".

Collect the distinct parent-customer values from the matched contacts. For each, call `dynamics-365-sales-get-opportunities` with `potential-customer` set to it, and keep the open ones.

**Step 4: Report**

1. The campaign: name, last-sent-date, sends, opens, clicks.
2. Engaged people by CRM status: contact, lead, unknown to CRM, with counts.
3. A table of accounts with open pipeline: account, engaged people at it, number of open opportunities, total est-revenue, nearest est-close-date, owner.
4. Engaged leads: name, company, rating, owner.
5. Engaged people unknown to CRM: name and email only. Suggest the capture-campaign-leads prompt to create them as leads.

**Rules & Guidelines:**

* constant-contact tools are on the constant-contact server; dynamics-365-sales tools are on the dynamics-365-sales server.
* Read-only. Do NOT call `dynamics-365-sales-create-lead`, `dynamics-365-sales-update-opportunity`, `dynamics-365-sales-create-task`, `constant-contact-resend-campaign-to-non-openers` or any other create, update, add or resend tool.
* Do not claim the campaign caused an opportunity; report only that engaged people are at accounts with open pipeline.

**Validation:**

* If nobody engaged, report the campaign's totals and stop.
* If 500 engagement rows come back, say the list was truncated.
* Match emails case-insensitively.
