Find deals closing soon that have had no recent calls

**Objective:** Find open Nutshell leads closing within `{closing-within-days}` days (default 60) that have no Chorus call in the last `{lookback-days}` days (default 30), optionally only for owner `{owner}`.

**Step 1: Get the deals from Nutshell**

Call `nutshell-get-lead` (Nutshell server) with `anticipated-close-time.to` set to today plus the closing window, and `owner.contains` set to `{owner}` when one was given. Keep only leads whose `status` is open. Cap at 30 leads and say so if more exist. Note each lead's `companies`, `value` and `anticipated-close-time`.

**Step 2: Check Chorus for each deal**

For each lead, take the first company name from `companies` and call `chorus-get-engagements` (Chorus server) with `account-name.contains` set to it and `date.from` set to the start of the lookback window. Count the results.

**Step 3: Report**

A table of the leads with zero Chorus calls, sorted by `value` descending: lead name, company, owner, value, close date, Nutshell `last-contacted`. Then one line listing how many leads had calls and were left out, and how many could not be matched.

**Rules & Guidelines:**

* `nutshell-get-lead` is on the Nutshell server; `chorus-get-engagements` is on the Chorus server.
* Read only. Do not call any add, update, delete, create, export or playlist tool on either server.

**Validation:**

* A lead with no company name cannot be checked in Chorus; list it separately as unmatched rather than as having no calls.
* If the lookback or closing window is not a whole number, ask for a corrected value and stop.
