Add people from your Chorus calls to Capsule CRM

**Objective:** Find the external people on Chorus calls from the last {lookback-days} days (default 30), optionally only for account {account-name}, who are not people in Capsule CRM, and add the ones the user approves.

**Step 1: Collect the participants in Chorus**

Call `chorus-get-engagements` with `date.from` set to the start of the window, and `account-name.contains` set to {account-name} when it is given. For each conversation, call `chorus-get-conversation-participants` with its `conversation-id`. Keep participants with an email and no `user-id` (people outside your company). Remove duplicates by email.

**Step 2: Check Capsule CRM**

For each email, call `capsule-crm-get-party` with `email`. Anyone found is already a contact; drop them. For each remaining person, call `capsule-crm-get-party` with `name.contains` set to their company name (or the conversation's account name) to find their organization and its `party-id`.

**Step 3: Confirm**

Show a table of name, email, job title, company, Capsule organization (found or not found), and the number of calls they were on. Ask the user which people to add. Do not write until they answer.

**Step 4: Create and verify**

For each approved person, call `capsule-crm-add-party` with `type` set to person, `first-name` and `last-name` split from the Chorus name, `email`, `job-title` from the Chorus title, and `organisation-id` set to the organization's `party-id` when one was found. If a name is a single word, ask for the missing part rather than guess. Then call `capsule-crm-get-party` with each `email` and confirm the person exists.

**Rules & Guidelines:**

* Tools whose names start capsule-crm are on the capsule-crm server; tools whose names start chorus are on the chorus server.
* The only write tool is `capsule-crm-add-party`, for people only and once per approved person. Do not create organizations, and do not call `capsule-crm-update-party`, `capsule-crm-add-note` or any other Capsule write, or any Chorus add, create, update or export tool.

**Validation:**

* If every participant is already in Capsule CRM, say so and stop.
* When the organization is not found, list the person as not linked and let the user decide; do not link them to a partial name match.
* Call `chorus-get-users` once and skip participants whose email domain matches a Chorus user's email domain; they are colleagues, not contacts.
