Know which open cases a customer already raised on a call

**Objective:** For the customer `{account-name}`, list the open Dynamics 365 Sales cases and show, for each, whether it came up in a Chorus conversation in the last `{lookback-days}` days (default 30), so account managers go into their next call knowing the service picture.

**Step 1: Open cases (Dynamics 365 Sales)**

Call `dynamics-365-sales-get-incidents` with `customer` = `{account-name}` (retry with `customer.contains`) and `status` = active. Keep `case-number`, `case-title`, `priority`, `case-type`, `created-on`, `resolve-by` and `owner`. If there are none, say the customer has no open cases and stop.

**Step 2: Recent conversations (Chorus)**

Call `chorus-get-engagements` with `account-name` = `{account-name}` (retry with `account-name.contains`) and `date.from` = today minus `{lookback-days}` days. Call `chorus-get-emails` with `account-name.contains` and `sent-time.from` for the same window.

**Step 3: Match**

For each case, look in the conversations' `subject` and `meeting-summary`, and in the email names, for the case number, the product, or the key words of the case title. Record which conversations mention it.

**Step 4: Report**

* A table of open cases: case number, title, priority, age in days, resolve-by, and "discussed on <date>" or "not discussed".
* Issues raised in the conversations that match no open case, listed separately, as possible cases not yet logged.

**Rules & Guidelines:**

* `dynamics-365-sales-get-incidents` is on the Dynamics 365 Sales server. `chorus-get-engagements` and `chorus-get-emails` are on the Chorus server.
* This prompt is read-only. Do not call `dynamics-365-sales-create-case`, `dynamics-365-sales-update-case`, `dynamics-365-sales-create-note` or any Chorus action tool. If the user wants an unlogged issue opened, tell them to use the `open-support-case` prompt on the Dynamics 365 Sales server.
* Quote no more than a sentence from any summary.

**Validation:**

* A word match is a lead, not proof: say which words matched.
* If Chorus holds nothing for the account, still list the cases and say no conversations were found under the name searched.
