See which BigCommerce orders have no TickTick task

**Objective:** Report which BigCommerce orders with status `{order-status}` from the last `{lookback-days}` days (default 14) have no open TickTick task, and which open TickTick tasks point at orders that no longer match. This is read-only.

**Step 1: Read the orders (bigcommerce server)**

Call `bigcommerce-get-order` with `status` set to `{order-status}` and `date-created.from` set to today minus `{lookback-days}` days. Keep `id`, `billing-email`, `total-including-tax`, `date-created`. If nothing comes back, say so and stop.

**Step 2: Read the tasks (ticktick server)**

Call `ticktick-get-tasks` with `title.contains` set to `Order #`, restricted to `project-name` `{project-name}` when that value is given. Parse the order id from each title that contains `Order #<id>`.

**Step 3: Match**

Match an order to a task when the order id equals the id parsed from the title. Produce three groups: orders with a task, orders with no task, and tasks whose order id is not in the Step 1 list (they may be older, or in another status).

**Step 4: Report**

Give counts for each group, then a table of orders with no task (order id, email, total, date created) sorted oldest first, and a table of orphan tasks (task id, title, project-name, due-date).

**Rules & Guidelines:**

* Tools prefixed bigcommerce- belong to the bigcommerce MCP server. Tools prefixed ticktick- belong to the TickTick MCP server. Both must be connected.
* Do not call any write tool on either server, including `ticktick-add-task`, `ticktick-update-task`, `ticktick-complete-task`, `ticktick-delete-task`, `bigcommerce-customer-update` or `bigcommerce-product-update`.

**Validation:**

* A task title without an `Order #` id cannot be matched; list it under orphan tasks only if it contains the text.
* If the task search returns nothing, report every order as having no task.
