Turn Chorus call action items into Capsule CRM tasks

**Objective:** Create Capsule CRM follow-up tasks from the action items in Chorus conversation {conversation-id}, each due {due-in-days} days from today (default 3) unless the summary gives a date.

**Step 1: Read the conversation in Chorus**

Call `chorus-get-engagements` with `conversation-id` set to {conversation-id}. If nothing comes back, or the meeting summary is empty, say so and stop. Take the subject, date, rep name, rep `user-email`, account name, opportunity name and meeting summary.

**Step 2: Extract the action items**

List the follow-ups our side committed to in the summary: sending material, booking the next meeting, getting an answer. Leave out what the customer promised to do. Give each a short description and any date the summary mentions.

**Step 3: Resolve the Capsule CRM records**

- Call `capsule-crm-get-party` with `name.contains` set to the account name and take the organization `party-id`.
- If there is an opportunity name, call `capsule-crm-get-opportunity` with `name.contains` and take its `opportunity-id`.
- Call `capsule-crm-get-user` with `name` set to the rep name, and keep the user whose `from-email` or `username` matches the rep's Chorus email. If none matches, leave the owner unset and say so.

**Step 4: Check for existing tasks**

Call `capsule-crm-get-task` with the `party-id` and look at tasks with no `completed-date`. Mark any action item that an open task already covers, and leave it out unless the user asks for it.

**Step 5: Confirm**

Show a table of description, due date, owner, and the linked opportunity or contact. Ask the user which to create. Do not write until they answer.

**Step 6: Create and verify**

For each approved item, call `capsule-crm-add-task` with `description`, `due-on`, `detail` (the conversation subject and date), `owner-id` when resolved, and the `opportunity-id` when there is one, otherwise the `party-id`. Then call `capsule-crm-get-task` with the `party-id` and confirm each new task 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-task`, once per approved item. Do not call `capsule-crm-update-task`, `capsule-crm-add-note`, `capsule-crm-update-opportunity` or any other Capsule write, and do not call any Chorus add, create, update or export tool.

**Validation:**

* If the summary has no action items for our side, say so and create nothing.
* If the account is not in Capsule CRM, offer to create the tasks unlinked, and only do so if the user agrees.
* Due dates must be today or later; move a past date from the summary to today and say so.
