Find closing deals that have gone quiet in Chorus

**Objective:** Find open Salesforce opportunities closing in the next {close-within-days} days (default 30) whose accounts have had no Chorus call, meeting or email in the last {quiet-days} days (default 14). If {owner} is given, only look at that owner's opportunities.

**Step 1: List the closing opportunities in Salesforce**

Call `salesforce-get-opportunity` with closed = false and close-date.to = today plus the close-within days. If {owner} is not empty, also pass owner.contains = {owner}. If more than 50 come back, keep the 50 with the earliest close dates and say how many were left out.

**Step 2: Check each account in Chorus**

For each distinct account-name among those opportunities:

* Call `chorus-get-engagements` with account-name = that name and date.from = today minus the quiet days. If nothing comes back, retry once with account-name.contains using the distinctive part of the name.
* Call `chorus-get-emails` with account-name.contains set the same way and sent-time.from = the same date.

**Step 3: Report**

Group the opportunities into three tables, each with opportunity, account, owner, stage, amount, close date, last conversation date and last email date:

1. **Silent:** no conversation and no email in the window.
2. **Email only:** emails but no call or meeting.
3. **Active:** at least one call or meeting.

Sort each table by close date. End with the total amount at stake in the Silent table.

**Rules & Guidelines:**

* `salesforce-get-opportunity` is on the Salesforce server. `chorus-get-engagements` and `chorus-get-emails` are on the Chorus server.
* This is read-only. Do not call `salesforce-update-opportunity`, `salesforce-add-task` or any other write tool. Recommend follow-ups in the report instead.

**Validation:**

* If no opportunities are closing in the window, say so and stop.
* An account Chorus does not know at all belongs in Silent, marked "account not found in Chorus", since Chorus may spell the name differently.
