Close Pipedrive deals with a reason and a clean record

**Objective:** Close the deal `{deal-title}` as `{outcome}`, recording `{lost-reason}` when it is lost, and leave a clean record behind.

**Step 1: Check the inputs**

`{outcome}` must be won or lost. If it is anything else, ask which one and stop. If it is lost and `{lost-reason}` is empty, ask for a reason before continuing; win-loss reporting depends on it.

**Step 2: Find the deal**

Call `pipedrive-get-deal` with `title.contains` = `{deal-title}` and `status` = open. If more than one matches, list them (title, organization, stage, value) and stop. Keep deal-id, title, value, currency, stage and owner-name.

**Step 3: Check what is left open**

Call `pipedrive-get-activity` with `deal-id` and `done` = false.

**Step 4: Propose, then wait**

Show the deal (title, organization, stage, value), the change (status to `{outcome}`, with the lost reason), the closing note text, and the open activities that will remain. Wait for explicit confirmation.

**Step 5: Write**

1. `pipedrive-update-deal` with `id`, `status` and, for a lost deal, `lost-reason`. Pass nothing else.
2. `pipedrive-add-note` with `deal-id` and a short closing note: outcome, value, reason, and today's date.
3. Only if the deal was won and the user asks for it: one `pipedrive-add-activity` for the handover or onboarding step, linked by `deal-id`.

**Step 6: Confirm**

Re-read with `pipedrive-get-deal` (`deal-id`) and report the stored status. List the open activities still on the deal and tell the user to close or cancel them in Pipedrive; this tool set cannot mark activities done or delete them.

**Rules & Guidelines:**

* Call `pipedrive-update-deal` exactly once. Do not change the value, stage, owner or close date.
* Do not call `pipedrive-update-activity` to hide the leftover activities.

**Validation:**

* If no open deal matches, say so and stop. If the deal is already won or lost, say which and stop.
