See every donor conversation on one timeline

**Objective:** For the donor `{donor-id}`, list the Granola meetings they attended or were invited to in the last {lookback-days} days (default 90) and compare them with the contacts logged in DonorPerfect.

**Step 1: Get the donor's email addresses**

Call `donorperfect-get-donor` with `donor-id`, then `donorperfect-get-address` with `donor-id`. Collect every distinct `email`. If there is none, report that meetings cannot be matched and stop.

**Step 2: Find their meetings in Granola**

For each email, call `granola-get-attendee` with `email` and `note-created.from` set to the start of the window, and `granola-get-invitee` the same way. Collect the distinct `note-id` values. For each, call `granola-get-note` with `id` to get `title`, `scheduled-start`, `owner-name` and `summary`.

**Step 3: Get logged contacts**

Call `donorperfect-get-contact` with `donor-id` and `contact-date.from` set to the start of the window.

**Step 4: Report**

A timeline, newest first, mixing meetings (date, title, owner, one-line summary, attended or invited only) and logged contacts (date, activity-code, by-whom, comment). Mark each meeting "logged" if a contact exists within one day of it, otherwise "not logged".

**Rules & Guidelines:**

* Granola tools (`granola-*`) read meetings; DonorPerfect tools (`donorperfect-*`) read donors. Both servers must be connected.
* This is read-only. Never call `donorperfect-save-pledge`, `donorperfect-save-gift`, `donorperfect-set-flag`, `donorperfect-save-address`, `donorperfect-save-donor`, `donorperfect-save-contact`, `donorperfect-save-other-info`, `donorperfect-save-link`.
* Meeting notes and transcripts are private to their owners and attendees. Only report content the tools returned for the signed-in user, and do not quote transcript text beyond what the report needs.
**Validation:**

* If no meetings are found, say so and still show the logged contacts.
* If the donor does not exist, report that and stop.
