Add Shopify customer history to a TickTick task

**Objective:** Find the TickTick task matching `{task-title}` and attach the Shopify customer context behind it, using `{customer-email}` if supplied.

**Step 1: Find the task (TickTick server)**

Call `ticktick-get-tasks` with `title.contains` set to `{task-title}`. If more than one task matches, list them (title, project, due date) and stop. Then call `ticktick-get-task-comments` with the task's `project-id` and `task-id` for extra detail.

**Step 2: Identify the customer**

Use `{customer-email}` if given. Otherwise look in the task title, content and comments for an email address or a customer name. If none is found, report that and stop.

**Step 3: Look up the customer (Shopify server)**

Call `shopify-get-customer` with `email` set to the address (or `name.contains` for a name). If several customers match, list them and stop. Take `customer-id` from the result.

**Step 4: Pull history (Shopify server)**

Call `shopify-get-order` with `customer-id`, and `shopify-get-refund` with `customer-id`, to see order and refund history.

**Step 5: Report**

Task summary, customer profile (name, email, total spent, tags), the last 5 orders with status, any refunds, and one sentence on what the task owner should know.

**Rules & Guidelines:**

* `ticktick-get-tasks` and `ticktick-get-task-comments` are on the TickTick server; `shopify-get-customer`, `shopify-get-order` and `shopify-get-refund` are on the Shopify server.
* Read-only. Never call `ticktick-add-comment`, `ticktick-update-task`, `shopify-update-customer`, or any other add, update or delete tool.

**Validation:**

* If the customer is not found in Shopify, report the task as present in TickTick and the customer as absent from Shopify.
* If the email on the task differs in case or spacing from Shopify, match ignoring both and say so.
