See which open OnePageCRM deals have gone quiet

**Objective:** List open OnePageCRM deals whose contact has not appeared in any Granola meeting in the last `{lookback-days}` days (default 30), so the owner can see which deals are going quiet. Limit to deals owned by user id `{owner-id}` when given.

**Step 1: Open deals (onepagecrm server)**

Call `onepagecrm-get-deal` with `status` set to pending (if the status value is rejected, call without it and drop won and lost deals yourself) and `owner-id` set to `{owner-id}` when provided. Keep name, amount, stage, expected-close-date, contact-id and contact-name.

**Step 2: Contact emails (onepagecrm server)**

For each distinct contact-id call `onepagecrm-get-contact` with `id` set to the contact id and keep the email. Contacts without an email cannot be checked: list them separately.

**Step 3: Recent meetings (granola server)**

Call `granola-get-attendee` with `email` set to each contact email and `note-created.from` set to the start of the lookback window. A deal has recent coverage if any row returns.

**Step 4: Report**

Table of deals with no recent meeting: deal name, contact, amount, stage, expected-close-date, date of the last meeting if one exists outside the window (call `granola-get-attendee` again without the date filter and take the newest). Sort by amount, largest first. Then the list of deals that could not be checked.

**Rules & Guidelines:**

* `granola-get-attendee` is on the granola server. `onepagecrm-get-deal` and `onepagecrm-get-contact` are on the onepagecrm server.
* Read-only. Never call `onepagecrm-update-deal`, `onepagecrm-add-action` or any other write tool.

**Validation:**

* If there are no open deals, say so and stop.
* Match emails case-insensitively; a contact with no Granola row is reported as no meeting found, not as an error.
