Line up a Drip campaign with its Salesforce twin

**Objective:** Compare the people on the Drip campaign named `{drip-campaign-name}` with the members of the Salesforce campaign named `{salesforce-campaign-name}`, matching on email.

**Step 1: Drip audience**

Call `drip-get-campaign-subscriber` with `campaign-name` set to `{drip-campaign-name}`. If nothing comes back, retry with `campaign-name.contains`; if that matches more than one campaign, list the campaign names and stop so the user can pick. Keep `email`, `first-name`, `last-name`, `status` and `lead-score`.

**Step 2: Salesforce audience**

Call `salesforce-get-campaign-member` with `campaign-name` set to `{salesforce-campaign-name}`, using the same `campaign-name.contains` fallback and the same stop rule. Keep `email`, `name`, `type`, `status` and `responded`.

**Step 3: Match on email**

Put each person in exactly one group: on both, only in Drip, only in Salesforce.

**Step 4: Report**

* Counts for each group.
* A table of people only in Drip (email, name, Drip status, lead score).
* A table of people only in Salesforce (email, name, member type, member status, responded).
* Among people on both: anyone unsubscribed in Drip but marked responded in Salesforce, listed separately.

**Rules & Guidelines:**

* `drip-get-campaign-subscriber` is on the Drip server; `salesforce-get-campaign-member` is on the Salesforce server.
* This prompt is read-only. Do NOT call `drip-add-subscriber-to-campaign`, `drip-remove-subscriber-from-campaign` or `salesforce-update-campaign`.

**Validation:**

* Compare emails case-insensitively. A Salesforce member with no email cannot be matched; list them under only in Salesforce and say why.
* If either campaign has no members, say which, and report the other side as all unmatched.
