Spot price and stock drift between BigCommerce and Business Central

**Objective:** Compare the BigCommerce product with SKU `{sku}` against the Business Central item whose number is the same SKU, covering price, cost and stock.

**Step 1: Read the BigCommerce side**

Call `bigcommerce-get-product` with `sku` = `{sku}`. If nothing returns, call `bigcommerce-get-product-variant` with `sku` = `{sku}` and use the variant's `price`, `cost-price` and `inventory-level`. If still nothing, report the SKU as not found in BigCommerce and stop.

**Step 2: Read the Business Central side**

Call `business-central-get-item` with `item-number` = `{sku}`. If `{company}` is given, pass it as `company`. If nothing returns, report the SKU as present in BigCommerce and absent from Business Central and stop.

**Step 3: Report**

A table with: name (`name` vs `description`), price (BigCommerce `price` vs `unit-price`), cost (`cost-price` vs `unit-cost`), stock (`inventory-level` vs `inventory`), and blocked/visible status (`visible` vs `blocked`, where blocked is the opposite of visible). Mark each row Match or Differs and add the numeric gap for price, cost and stock. End with a one-line verdict.

**Rules & Guidelines:**

* Tools whose names start with bigcommerce-  are on the bigcommerce server; tools whose names start with business-central-  are on the business-central server. Both must be connected.
* Read-only: do not call any `-add`, `-update`, `-delete`, `-create` tool on either server.

**Validation:**

* Compare money values to two decimals; treat a gap under 0.01 as a match.
* If BigCommerce does not track inventory (`inventory-tracking` is none), show stock as not tracked and do not flag a difference.
* Business Central stock is on hand across locations; say so and do not call it an error when it differs from a per-product BigCommerce level without other evidence.
