Move Capsule CRM deals between milestones the right way

**Objective:** Move the opportunity `{opportunity-name}` to the milestone `{milestone-name}`, recording the lost reason `{lost-reason}` if it is being lost, and add `{note}` to its history if given.

**Step 1: Find the opportunity**

Call `capsule-crm-get-opportunity` with name.contains = {opportunity-name}. If more than one matches, list name, party, owner, milestone and value, and stop and ask which one. Keep the opportunity-id and current milestone-name. If closed-on-date is already set, tell the user the deal is already closed and ask whether to reopen it.

**Step 2: Find the milestone**

Call `capsule-crm-get-milestone` with name = {milestone-name}; if nothing matches, call it with no filter and list the available milestones, then stop. Keep the milestone-id, probability and complete flag. If the target is the milestone the deal is already at, say so and stop.

**Step 3: Lost reason (only for a lost milestone)**

When the target milestone is complete with probability 0, a lost reason is needed. Call `capsule-crm-get-lost-reason` with name.contains = {lost-reason}. If {lost-reason} is blank or matches nothing or several, list all lost reasons and ask the user to pick one. Keep the lost-reason-id.

**Step 4: Confirm**

Show: opportunity, party, current milestone, new milestone, the new probability the milestone implies, the lost reason if any, and the note if any. Wait for an explicit yes.

**Step 5: Write**

1. Call `capsule-crm-update-opportunity` once, with id, milestone-id, and lost-reason-id only when losing. Pass no other fields.
2. If {note} is given, call `capsule-crm-add-note` once, with opportunity-id and content = {note}.

**Step 6: Verify**

Call `capsule-crm-get-opportunity` with opportunity-id and confirm milestone-name now matches, and for a lost deal that lost-reason-name is set. Report the before and after.

**Rules & Guidelines:**

* The only write tools this prompt may call are `capsule-crm-update-opportunity` and `capsule-crm-add-note`, each at most once, after confirmation.
* Do not change the value, owner, probability, name or expected close date, even if they look wrong; mention them instead.
* Do not create a project for a won deal; the user can run the start-project-from-won-deal prompt.

**Validation:**

* If the update fails, report the error and do not add the note.
