Find engaged Drip subscribers sales has never seen

**Objective:** List active Drip subscribers with a lead score of at least `{min-lead-score}` (default 50) who do not exist in Salesforce as a contact or a lead. Check at most `{max-records}` subscribers (default 50).

**Step 1: Engaged subscribers in Drip**

Call `drip-get-subscriber` with `status` set to active, `lead-score.min` set to the minimum score and `max-records` set to the limit. Keep `email`, `first-name`, `last-name`, `lead-score`, `lifetime-value`, `tags` and `country`.

If Drip returns nothing, report that no subscriber meets the score and stop.

**Step 2: Check each email in Salesforce**

For each subscriber, call `salesforce-get-contact` with `email` set to the subscriber's `email`. If no contact comes back, call `salesforce-get-lead` with the same `email`. A subscriber is missing only when both calls return nothing.

**Step 3: Report**

A table of the missing subscribers, highest lead score first: email, name, lead score, lifetime value, tags, country. Below it, one line each for: how many subscribers were checked, how many matched a contact, how many matched a lead, and how many are missing.

**Rules & Guidelines:**

* `drip-get-subscriber` is on the Drip server; `salesforce-get-contact` and `salesforce-get-lead` are on the Salesforce server.
* This prompt is read-only. Do NOT call `salesforce-add-lead`, `salesforce-add-contact` or `drip-update-subscriber`. If the user wants the gaps filled, point them to the create-salesforce-leads-from-drip prompt.

**Validation:**

* Compare emails case-insensitively and ignore surrounding spaces.
* If a subscriber has no email, skip it and say how many were skipped.
* If the limit was reached, say the list may be incomplete and suggest raising the max-records or min-lead-score parameter.
