Find open TickTick tasks for Zendesk tickets already solved

**Objective:** Find open TickTick tasks that refer to Zendesk tickets solved in the last `{lookback-days}` days (default 14).

**Step 1: List solved tickets (zendesk server)**

Call `zendesk-get-ticket` with status solved and created.from set to the date `{lookback-days}` days ago (14 if empty). Keep ticket-id, subject and solved-date.

**Step 2: Find open tasks (TickTick server)**

Call `ticktick-get-tasks` for open tasks, with title.contains set to `ZD` when `{task-prefix}` is empty, otherwise to `{task-prefix}`. For each returned task, extract the ticket number from the title and match it to the solved tickets from Step 1.

**Step 3: Report**

Table of task title, project-name, due-date, ticket-id, solved-date. Say how many open tasks you scanned and how many had no recognizable ticket number.

**Rules & Guidelines:**

* Servers: ticktick-* tools are on the TickTick MCP server and zendesk-* tools are on the zendesk MCP server. The shared key is the Zendesk ticket id, which TickTick holds only as text in a task title (for example `[ZD #1234]`), so match with title.contains and never assume an exact link.
* Read-only. Do not call `ticktick-complete-task`, `ticktick-complete-multiple-tasks`, `ticktick-delete-task` or any other write tool; the user can use the complete prompt for that.

**Validation:**

* If no tickets were solved in the window, say so and stop.
* A task whose ticket is not in the solved list is not stale. Never infer a status from the title.
