Set up new Dynamics GP customers once, addresses and email included

**Objective:** Set up `{customer-name}` as a new customer with id `{customer-id}` (default proposed) from `{details}`, without creating a duplicate, after the user confirms.

Pass `{company}` as `company` on every call (if it is empty, omit `company` and the default company is used). Pass a generous `max-records` (1000). If a result comes back with exactly that many rows, say the result may be truncated.

**Step 1: Duplicate check**

* `dynamics-gp-get-rm-customer` with `customer-name.contains` using the most distinctive word of `{customer-name}`, and again by city or phone if given. Show likely matches and stop if one looks like the same business.
* `dynamics-gp-get-rm-prospect` with `customer-name.contains`: if the business is already a prospect, suggest the `convert-prospect-to-customer` prompt instead and stop unless the user says continue.

**Step 2: Validate references**

* If a salesperson is named, confirm it with `dynamics-gp-get-rm-salesperson`.
* If `{customer-id}` is empty, propose one in the style of existing ids (look at a few from Step 1) and check it is unused with `dynamics-gp-get-rm-customer` by `customer-id`.

**Step 3: Confirm**

Show the user exactly what will be written, field by field, and ask for explicit confirmation. Do nothing further without a clear yes. Show id, name, class, address, city, state, zip, country, phone, contact, terms, salesperson, email, and any ship-to address.

**Step 4: Write**

1. Call `dynamics-gp-rm-customer-add` once with the confirmed customer fields.
2. If a separate ship-to address was given, call `dynamics-gp-rm-customer-address-add` once with `customer-id`, `address-code` and its fields.
3. If an email was given, call `dynamics-gp-rm-customer-address-email` once with `customer-id`, `address-code` (the primary address code unless it belongs to the ship-to) and `email-address`.

Run each step only if the one before succeeded. If a later step fails, say which parts were created. Do not retry a failed write automatically. Report the error exactly as returned.

**Step 5: Verify**

Call `dynamics-gp-get-rm-customer` by `customer-id` and report the stored record.

**Rules & Guidelines:**

* The only write tools this prompt may call are `dynamics-gp-rm-customer-add`, `dynamics-gp-rm-customer-address-add` and `dynamics-gp-rm-customer-address-email`, once each, after Step 3.
* Do not set a credit limit or hold; neither is part of onboarding here.

**Validation:**

* If the proposed customer id is taken, propose another and confirm again.
