Chase overdue Sage Intacct invoices from an Asana project

**Objective:** Find Sage Intacct invoices overdue by more than `{days-overdue}` days (default 30) with at least `{min-amount}` due (default 0.01), and create one follow-up task per invoice in the Asana project `{asana-project}`, skipping invoices that already have a task.

**Step 1: Read overdue invoices**

Call `intacct-get-invoice` with `due-date.to` = today minus `{days-overdue}` days and `total-due.min` = `{min-amount}`. Keep `invoice-number`, `customer-id`, `customer-name`, `due-date` and `total-due`. If nothing comes back, report that there are no overdue invoices and stop.

**Step 2: Add customer contact detail**

For each distinct `customer-id`, call `intacct-get-customer` with it and keep `email` and `customer-rep-name`.

**Step 3: Find the Asana project**

Call `asana-get-project` with `name` = `{asana-project}`. If zero or several projects come back, say so and stop without writing.

**Step 4: Skip existing tasks**

Call `asana-get-tasks` with `projects.contains` = `{asana-project}` and `completed` = false. An invoice already has a task if an open task's `name` contains its `invoice-number`. Drop those.

**Step 5: Confirm**

Show the user a table of the tasks you would create: task name "Collect invoice <invoice-number> - <customer-name>", amount due, due date, days overdue, customer email, and customer rep. Ask the user to confirm, and let them remove rows. Do not continue without a clear yes.

**Step 6: Create and confirm**

For each confirmed row, call `asana-create-task` once with `name` as above, `project-ids` = the Asana `project-id`, `due-on` = today plus 7 days (ISO), and `notes` listing the invoice number, customer, amount due, original due date, customer email and customer rep. Report each returned `permalink-url`, and list any that failed with the error.

**Rules & Guidelines:**

* `intacct-get-invoice` and `intacct-get-customer` are on the intacct server. `asana-get-project`, `asana-get-tasks` and `asana-create-task` are on the asana server.
* `asana-create-task` is the only tool that may write, once per confirmed invoice. Do NOT call `asana-update-task`, `asana-create-comment`, `intacct-update-customer` or any other intacct create or update tool.
* Never create more than 25 tasks in one run. If there are more, create the 25 largest by `total-due` and tell the user how many remain.

**Validation:**

* If a customer has no email in Intacct, still create the task and write "no email on file" in the notes.
* If `asana-create-task` fails for one invoice, report it and continue with the rest.
