Spot where Freshdesk ratings and Simplesat sentiment disagree

**Objective:** Compare customer satisfaction recorded in Freshdesk with Simplesat for the last {lookback-days} days (default 14), optionally for one agent {agent-id}.

**Step 1: Freshdesk ratings**

Call `freshdesk-get-satisfaction-ratings` with created-at.from set to the start of the window and agent-id = {agent-id} when given. Keep ticket-id, rating, user-id and agent-id.

**Step 2: Simplesat responses**

For each rated ticket (cap at 40), call `simplesat-get-response` with ticket-id. For each response found, call `simplesat-list-answers` with response_id = the response id and note the sentiment.

**Step 3: Compare**

Match on ticket id. Treat a Freshdesk rating in the bottom third of the scale as negative and the top third as positive. List every ticket where the two disagree, plus counts of tickets rated only in Freshdesk, only in Simplesat, and in both.

**Step 4: Report**

A table: ticket id, Freshdesk rating, Simplesat sentiment, agreement. Finish with the totals.

**Rules & Guidelines:**

* Tools prefixed reshdesk- are on the Freshdesk server; tools prefixed simplesat- are on the Simplesat server. Both must be connected.
* Read-only. Do not call any add, update, delete, reply or send tool on either server.

**Validation:**

* If either side returns nothing for the window, say so and stop.
* Rating scales differ between systems; state the mapping you used.
