Find Akeneo products with no Business Central item

**Objective:** Find Akeneo products for brand `{brand}` (default: all brands) that have no Business Central item, up to `{max-products}` products (default 50).

**Step 1: Read the products from Akeneo**

Call `akeneo-get-product` (Akeneo server) with `brand` set to `{brand}` if given, `enabled` true, and `max-records` set to `{max-products}`. Keep `identifier`, `product-name`, `brand`, `family` and `uuid` for each product. If nothing comes back, say so and stop.

**Step 2: Look each identifier up in Business Central**

For each product call `business-central-get-item` (Business Central server) with `item-number` set to the product `identifier`, and `company` set to `{company}` if given. The Akeneo `identifier` (the SKU) is matched to the Business Central `item-number`. Match exactly; do not guess near matches. If a product has no exact match, try once with `description.contains` set to its `product-name` and mark any hit as a possible match, not a confirmed one.

**Step 3: Report**

Give three lists: products with a confirmed item, products with a possible match only (show both identifiers), and products with no item at all. For matched pairs show `item-number`, `blocked`, `unit-price` and `inventory`. End with counts for each list.

**Rules & Guidelines:**

* `akeneo-get-product` is on the Akeneo server; `business-central-get-item` is on the Business Central server. Both servers must be connected.
* This is read-only. Do not call `business-central-create-item`, `business-central-update-item`, `akeneo-add-product`, `akeneo-update-product` or `akeneo-delete-product`.
* Never modify or create anything to close a gap; only report it.

**Validation:**

* If Business Central returns more than one item for an identifier, list them all and flag the product as ambiguous.
* If a tool returns an error, say which server it came from and stop rather than reporting partial results as complete.
