Find Attio deals put at risk by open Zendesk tickets

**Objective:** Find Attio deals in stage `{deal-stage}` whose customer has open Zendesk tickets at priority `{priority}` (default urgent).

**Step 1: List the deals**

Call `attio-get-record-deals` (Attio server) with `deal-stage` set to the stage and `max-records` 50. If none come back, say so and stop. Keep `deal-name`, `deal-value`, `deal-owner` and `associated-company`.

**Step 2: Find each company's domains**

For each distinct `associated-company`, call `attio-get-record-companies` (Attio server) with `name` set to that company. Keep `domains`. If a name matches several companies, mark that deal as ambiguous and skip it.

**Step 3: Check Zendesk**

For each company, call `zendesk-get-organization` (Zendesk server) with `domain-names.contains` set to its domain; keep the organization `name`. Then call `zendesk-get-ticket` (Zendesk server) with `organization-name`, `priority` set to the requested priority and `status` set to open. Note that `status` values depend on the Zendesk account; if a filter returns nothing, retry without `status` and exclude solved and closed tickets yourself.

**Step 4: Report**

A table of deals with at least one such ticket: deal, value, owner, company, ticket count, oldest ticket `created-date`, newest `subject`. Sort by deal value, largest first. Then list companies with no Zendesk organization match separately, and the count of deals with no matching tickets.

**Rules & Guidelines:**

* `attio-*` tools are on the Attio server; `zendesk-*` tools are on the Zendesk server.
* Read-only. Do not call `attio-update-deal`, `zendesk-update-ticket` or `zendesk-add-ticket-comment`.

**Validation:**

* Match on domain, never on a partial company name alone.
* Say how many companies were checked and how many had no Zendesk match, so a quiet result is not mistaken for a clean one.
