Find overdue NetSuite invoices that no one is chasing

**Objective:** Find open accounts receivable items in NetSuite that are past due as of `{as-of-date}` (default today) and report which have no open follow-up task in TickTick, limited to the customer `{customer}` when given.

**Step 1: Read overdue receivables (NetSuite)**

Call `netsuite-get-aropenitem` with `due-date.to` set to the as-of date, adding `customer` when `{customer}` is given and `max-records` of 100. Keep rows where `amount` minus `amount-applied` is greater than zero. If none, say so and stop.

**Step 2: Find follow-up tasks (TickTick)**

For each item call `ticktick-get-tasks` with `title.contains` set to the item's `document-number` and `status` open. If nothing matches, retry once with `title.contains` set to the `customer` name.

**Step 3: Report**

A table with `document-number`, `customer`, `due-date`, open balance, days overdue, and the matching task title, due date and project (or NONE). Order by days overdue, then list the NONE rows separately with a total balance.

**Rules & Guidelines:**

* `netsuite-get-aropenitem` is on the NetSuite server; `ticktick-get-tasks` is on the TickTick server.
* This prompt is read-only. Do NOT call any TickTick write tool (`ticktick-add-task`, `ticktick-update-task`, `ticktick-complete-task`, `ticktick-add-comment`, `ticktick-delete-task`, `ticktick-move-task`, `ticktick-batch-tasks`) or any NetSuite add or update tool.

**Validation:**

* If a document number matches several tasks, list them all and do not pick one.
* If TickTick returns nothing for the whole run, say the follow-up tasks may use a different naming convention.
