Find engaged email readers who have never given

**Objective:** Find Drip subscribers with a lead score of at least `{lead-score-min}` (default 50) who are not donors in DonorPerfect, or who are donors with no gifts. Check at most `{max-subscribers}` subscribers (default 50).

**Step 1: List engaged subscribers in Drip**

Call `drip-get-subscriber` with `lead-score.min` set to the minimum, `status` set to active, and `max-records` set to the limit.

**Step 2: Look each one up in DonorPerfect**

For each subscriber, call `donorperfect-get-donor` with `email` set to the subscriber's email. If nothing comes back, call `donorperfect-get-address` with the same email. If a donor is found, read their gift total and gift count from the donor record.

**Step 3: Report**

Two tables:

* **Not in DonorPerfect:** Drip person-id, name, email, lead score, lifetime value, tags.
* **In DonorPerfect with no gifts:** the same columns plus DonorPerfect donor-id.

Sort each by lead score, highest first, and give the counts checked and found under each table.

**Rules & Guidelines:**

* `drip-get-subscriber` is on the drip server. `donorperfect-get-donor` and `donorperfect-get-address` are on the donorperfect server.
* This prompt is read-only. Do not call `donorperfect-save-donor` to create the missing donors, and do not call any Drip action such as `drip-add-subscriber-tag` or `drip-add-subscriber-to-campaign`.
* Match on email only, ignoring case and surrounding spaces.

**Validation:**

* If no subscriber meets the lead score, say so and suggest a lower `lead-score-min`.
* If every subscriber is already a donor with gifts, say so; that is a valid result, not a failure.
