Add Capsule CRM contacts once, to the right organization

**Objective:** Add `{person-name}` as a person in Capsule CRM, with email `{email}`, working at `{organization-name}`, owned by `{owner-name}`. Any of the last three may be blank.

**Step 1: Check for duplicates**

* If {email} is given, call `capsule-crm-get-party` with email = {email}.
* Call `capsule-crm-get-party` with name = {person-name}.

If either returns a record, show it (name, organization, email, owner, party-id) and stop. Ask whether this is a different person before going on.

**Step 2: Resolve the organization (only if {organization-name} is given)**

Call `capsule-crm-get-party` with name = {organization-name}. Keep only rows whose type is organization.

* One match: use its party-id as the organisation-id.
* Several: list them and ask.
* None: propose creating the organization as well, and include that in the confirmation.

**Step 3: Resolve the owner (only if {owner-name} is given)**

Call `capsule-crm-get-user` with name = {owner-name}. Keep the user-id. If no single user matches, list close matches from name.contains and ask.

**Step 4: Split the name**

Use the last word of {person-name} as last-name and the rest as first-name. If {person-name} is a single word or the split is unclear (such as "van der Berg"), ask.

**Step 5: Confirm**

Show exactly what will be created: the organization (if new), then the person with first name, last name, email, organization and owner. Wait for an explicit yes.

**Step 6: Write**

1. If the organization is new, call `capsule-crm-add-party` with type = organisation, name = {organization-name} and owner-id, then call `capsule-crm-get-party` with name = {organization-name} to get its party-id.
2. Call `capsule-crm-add-party` with type = person, first-name, last-name, email, organisation-id and owner-id.

**Step 7: Verify**

Call `capsule-crm-get-party` with email = {email} (or name = {person-name}) and report the stored record and its party-id.

**Rules & Guidelines:**

* The only write tool this prompt may call is `capsule-crm-add-party`: at most once for the organization and once for the person, after confirmation.
* Never modify an existing record. Do not call `capsule-crm-update-party`.
* Only pass fields the user supplied; do not invent a phone number, job title or tags.

**Validation:**

* If creating the organization fails, stop and do not create the person.
