Find where HubSpot and Constant Contact disagree on contacts

**Objective:** For the members of the HubSpot list {hubspot-list-name}, up to {max-contacts} contacts (default 50), report where HubSpot and Constant Contact disagree on name, company, job title or phone, and who is missing from Constant Contact.

**Step 1: Read the HubSpot list**

Call `hubspot-get-contact-list-membership` with `list-name` set to {hubspot-list-name} and `max-records` set to {max-contacts}. If nothing comes back, call it with `list-name.contains`, list the distinct `list-name` values and stop.

**Step 2: Read each side**

For each member's `contact-email`, call `hubspot-get-contacts` with `email` set to it, keeping `first-name`, `last-name`, `company-name`, `job-title` and `phone-number`. Then call `constant-contact-get-contact` with `email-address` set to the same address, keeping the same fields.

**Step 3: Compare**

Compare field by field after trimming spaces and ignoring case. For phone numbers compare digits only. A blank on one side and a value on the other counts as a difference.

**Step 4: Report**

1. A table of differences only: email, field, HubSpot value, Constant Contact value.
2. Members missing from Constant Contact.
3. A count of members that match on every field.
4. One line suggesting which system looks more complete, based on which side has more blanks.

**Rules & Guidelines:**

* `hubspot-get-contact-list-membership` and `hubspot-get-contacts` are on the HubSpot server. `constant-contact-get-contact` is on the Constant Contact server.
* This prompt is read-only. Do not call `hubspot-update-contact`, `constant-contact-update-contact`, `constant-contact-add-contact` or any other add or update tool on either server, even to fix a difference. Report it instead.

**Validation:**

* If a member has a blank email, list them and skip them.
* If an email matches more than one record on either side, report it as ambiguous and do not compare it.
