Follow up webinar no-shows who have open Nutshell deals

**Objective:** For webinar `{webinar-name}`, find registrants who did not attend and who are Nutshell contacts with open leads, so a rep can send the recording or rebook them.

**Step 1: Find the webinar (GoTo Webinar server)**

Call `goto-webinar-get-webinar` with `webinar-name.contains` set to the name. If more than one webinar matches, list them and stop. If none match, say so and stop.

**Step 2: Registrants and attendees (GoTo Webinar server)**

Call `goto-webinar-get-registrant` and `goto-webinar-get-attendee`, each with the `webinar-key` from Step 1. A no-show is a registrant whose `registrant-key` does not appear in the attendee results. Cap the list at `{max-records}` registrants (default 100).

**Step 3: Match no-shows to Nutshell (Nutshell server)**

For each no-show call `nutshell-get-contact` with `name.contains` set to the last name and keep the contact whose `emails` include the registrant `email` (ignore case). Then call `nutshell-get-lead` with the contact `company-id` (or `person-id` when there is no company) and keep open leads.

**Step 4: Report**

A table of no-shows with a Nutshell contact and open lead: name, email, contact `owner`, lead `name`, `value`, `anticipated-close-time` and Nutshell link. Add the total number of no-shows and how many were not found in Nutshell. If recordings exist, optionally call `goto-webinar-get-recordingasset` with the `webinar-key` and mention the recording.

**Rules & Guidelines:**

* GoTo Webinar tools: `goto-webinar-get-webinar`, `goto-webinar-get-registrant`, `goto-webinar-get-attendee`, `goto-webinar-get-recordingasset`. Nutshell tools: `nutshell-get-contact`, `nutshell-get-lead`.
* Read only. Do NOT call `goto-webinar-delete-registrant`, `goto-webinar-add-registrant`, `nutshell-add-activity`, or any add, update or delete tool.

**Validation:**

* If everyone attended, say so and stop.
* If the webinar has not happened yet, say that no-shows cannot be determined and stop.
