Find Capsule CRM deals whose people attend your webinars

**Objective:** Find open Capsule CRM opportunities (owned by `{owner}` if given, otherwise all owners) where someone on the deal registered for or attended a GoTo webinar in the last `{lookback-days}` days (default 90), and rank them by how engaged they were.

**Step 1: Read open opportunities in Capsule CRM**

Call `capsule-crm-get-opportunity`, with `owner-name` set to `{owner}` if given. Keep only rows with no `closed-on-date`. If there are more than 25, keep the 25 with the nearest `expected-close-date` and say how many were left out. If there are none, say so and stop.

**Step 2: Get the emails on each deal**

For each opportunity, call `capsule-crm-get-party` with `name` set to its `party-name`. If the party is a person, use their `email`. If it is an organization, call `capsule-crm-get-party` with `organization-name.contains` set to the name and use the emails of the people returned (at most 10 per deal). Skip deals with no email and count them.

**Step 3: Check GoTo Webinar**

For each email, call `goto-webinar-get-attendee` with `email` and `date-attended.from` set to today minus the lookback, and `goto-webinar-get-registrant` with `email` and `registration-date.from`. Count per deal: webinars attended, total minutes attended, registrations with no attendance.

**Step 4: Report**

1. A table of engaged deals, most minutes attended first: opportunity, party, milestone, value, expected close, owner, people engaged, webinars attended (names), minutes attended, no-shows.
2. One line: how many open deals were checked, how many showed webinar engagement, how many had no email to check.
3. For the top three, one sentence suggesting the follow-up (for example which webinar topic to raise).

**Rules & Guidelines:**

* `capsule-crm-*` tools are on the capsule-crm server; `goto-webinar-*` tools are on the goto-webinar server. If either set is missing, say which server is not connected and stop.
* This prompt is read-only. Do NOT call `capsule-crm-update-opportunity`, `capsule-crm-add-task`, `capsule-crm-add-note`, `goto-webinar-add-registrant` or `goto-webinar-delete-registrant`.

**Validation:**

* Compare emails case-insensitively.
* If `{owner}` matches no opportunities, call `capsule-crm-get-user` with `name.contains` set to it and list the users found so the caller can correct the name.
* Leave deals with no webinar activity out of the table; only count them.
