Hand a rep's open Capsule CRM work to someone else in one pass

**Objective:** Hand over everything open that `{from-owner}` owns to `{to-owner}`: open opportunities, open projects and open tasks, plus the people and organizations they own when `{include-contacts}` is yes (default no).

**Step 1: Resolve both users**

Call `capsule-crm-get-user` with name = {from-owner}, and again with name = {to-owner}. Each must resolve to exactly one user, and they must differ. Keep the to-owner's user-id.

**Step 2: Inventory what will move**

* Call `capsule-crm-get-opportunity` with owner-name = {from-owner} and max-records = 500; keep rows with no closed-on-date.
* Call `capsule-crm-get-case` with owner-name = {from-owner}, status = open and max-records = 500.
* Call `capsule-crm-get-task` with owner-name = {from-owner}, status = open and max-records = 500.
* Only if {include-contacts} is yes, call `capsule-crm-get-party` with owner-name = {from-owner} and max-records = 1000.

**Step 3: Confirm**

Show the counts per kind, then the list of each (name, and for deals value and milestone). Closed deals, closed projects and completed tasks stay where they are. Let the user exclude items by name or number. Wait for an explicit yes.

**Step 4: Write**

Pass only id and owner-id = the to-owner's user-id:

* each opportunity with `capsule-crm-update-opportunity`
* each project with `capsule-crm-update-case`
* each task with `capsule-crm-update-task`
* each contact with `capsule-crm-update-party`, only when included

With more than 25 items in total, work in batches of 25 and report progress after each batch.

**Step 5: Verify**

Re-run the Step 2 reads for {from-owner}. Report how many of each kind moved, which were excluded, and any that failed or are still owned by {from-owner}.

**Rules & Guidelines:**

* Change owner-id and nothing else. Do not pass status, milestone, value, dates or names.
* Each record is updated at most once. Do not call any add tool.
* If an update fails, carry on and list the failures at the end.

**Validation:**

* If {from-owner} owns nothing open, say so and stop.
* If {include-contacts} is anything other than yes, leave contacts alone.
