Capture new Dynamics 365 Sales leads once, with a follow-up booked

**Objective:** Capture `{lead-name}` from `{company-name}` (email `{email}`) as a new lead about `{topic}`, without creating a duplicate, and schedule the first follow-up.

**Step 1: Duplicate check**

* If `{email}` is given, call `dynamics-365-sales-get-leads` with `email` = it and `dynamics-365-sales-get-contacts` with `email` = it.
* Otherwise call `dynamics-365-sales-get-leads` with `name` = `{lead-name}`, and `dynamics-365-sales-get-contacts` with `full-name` = `{lead-name}`.
* If `{company-name}` is given, call `dynamics-365-sales-get-accounts` with `account-name` = it.

Then decide:

* An open lead matches: show it and stop. Do not create another.
* A contact matches: the person is already known. Show the contact and its parent customer, and stop.
* Only the account matches: the company is an existing customer. Say so and ask whether to create the lead anyway (the account owner should be told).

**Step 2: Confirm**

Show the lead that will be created (first name, last name, company, email, topic, and any source, rating, phone or job title the user gave) and ask for one confirmation.

**Step 3: Create**

1. `dynamics-365-sales-create-lead` with `topic`, `last-name`, `first-name`, `company-name`, `email` and any other details given. Keep the returned `id`.
2. `dynamics-365-sales-create-task` with `subject` = "First contact: " plus the lead's name, `regarding-id` = the new lead's `id`, and `due-date` = the next working day.

**Step 4: Report**

The new lead's id and the follow-up task's id and due date.

**Rules & Guidelines:**

* The only write tools this prompt may call are `dynamics-365-sales-create-lead` and `dynamics-365-sales-create-task`, each once, after the confirmation.
* Split `{lead-name}` into first and last name at the last space; a single word is the last name.
* If `dynamics-365-sales-create-lead` fails, do not create the task.

**Validation:**

* If `{lead-name}` or `{topic}` is blank, ask for it and stop.
