Find open deals with no recent Chorus contact

**Objective:** For open deals closing by `{close-by-date}` (ISO date, default 60 days from today), report which have had a Chorus conversation in the last `{quiet-days}` days (default 21) and which have not.

**Step 1: Collect open deals (onepagecrm server)**

Call `onepagecrm-get-deal` with `status` set to pending and `expected-close-date.to` set to `{close-by-date}`. Keep id, name, company-id, company-name, amount, stage, expected-close-date and contact-name.

**Step 2: Check Chorus for each deal (chorus server)**

For each deal, call `chorus-get-engagements` with `account-name` set to the deal company-name and `date.from` set to today minus `{quiet-days}` days. If that returns nothing, retry with `account-name.contains`. Note the latest conversation date and any opportunity-name that matches the deal name.

For deals with no conversation, call `chorus-get-emails` with `account-name.contains` and `sent-time.from` the same date, to tell a silent deal from one run over email.

**Step 3: Report**

A table sorted by amount descending: deal, company, amount, stage, expected close, last conversation date, emails in window, and a flag of Quiet (nothing in either channel), Email only, or Active. Total the amount in each flag.

**Rules & Guidelines:**

* `onepagecrm-get-deal` is on the onepagecrm server; `chorus-get-engagements` and `chorus-get-emails` are on the chorus server.
* Read-only. Never call `onepagecrm-update-deal`, `onepagecrm-add-action` or any other add, update or delete tool. Recommend follow-ups in words only.
* Do not reproduce email bodies.

**Validation:**

* If no open deals match, say so and stop.
* If a company name finds no Chorus account, mark the deal Unmatched rather than Quiet, since the name may differ between systems.
