Find major donors nobody has talked to lately

**Objective:** Find DonorPerfect donors whose lifetime giving is at least `{min-lifetime-giving}` and who have had no Chorus conversation or email in the last `{lookback-days}` days (default 90).

**Step 1: Donors in DonorPerfect**

Call `donorperfect-get-donor` with gift-total.min set to `{min-lifetime-giving}` and max-records 100. If 100 come back, say the list was capped and suggest a higher threshold.

**Step 2: Recent touches in Chorus**

For each donor:

* If the donor has an email, call `chorus-get-conversation-participants` filtered by email, then `chorus-get-engagements` for each conversation-id, keeping those dated inside the window. Also call `chorus-get-emails` with the email as initiator-email and sent-time.from set to the start of the window.
* If the donor has an organization-name, call `chorus-get-engagements` with account-name.contains set to it and date.from set to the start of the window.

Record the most recent touch date and how it was matched (email or organization).

**Step 3: Report**

* **No recent touch:** donor-id, name or organization-name, gift-total, last-contribution-amount, email, and the date of the last Chorus touch at any time if you found one. Sort by gift-total, highest first.
* **Touched recently:** count only, plus the five with the oldest recent touch.
* **Cannot check:** donors with no email and no organization-name.

**Rules & Guidelines:**

* Tools named donorperfect-... are on the donorperfect server. Tools named chorus-... are on the chorus server.
* This prompt is read-only. Do NOT call any DonorPerfect write tool (`donorperfect-save-donor`, `donorperfect-save-contact`, `donorperfect-save-gift`, `donorperfect-save-pledge`, `donorperfect-save-address`, `donorperfect-save-other-info`, `donorperfect-save-link`, `donorperfect-set-flag`) or any Chorus write tool (`chorus-add-moment`, `chorus-add-playlist-moment`, `chorus-create-playlist`, `chorus-update-moment`, `chorus-update-playlist`, `chorus-update-playlist-moment`, `chorus-export-recordings`, `chorus-export-scorecards`).

**Validation:**

* If `{min-lifetime-giving}` is not a number, ask for one and stop.
* If no donors meet the threshold, say so and stop.
* Treat organization-name matches as weaker evidence than email matches and label them.
