Fix bounced emails on the HubSpot contacts that matter

**Objective:** Find the HubSpot contacts whose email addresses bounced in Constant Contact in the last {lookback-days} days (default 30), optionally only bounces of type {bounce-type} (default all types), and group them by HubSpot owner.

**Step 1: Collect bounces from Constant Contact**

Call `constant-contact-get-campaign-bounce` with `created-date.from` set to the date {lookback-days} days before today (YYYY-MM-DD), and with `bounce-type` set to {bounce-type} when it is given. Group by `email-address`, keeping the bounce types seen and the latest `created-date`. If none come back, say so and stop.

**Step 2: Match in HubSpot**

For each bounced address, call `hubspot-get-contacts` with `email` set to it. Keep `record-id`, name, `contact-owner`, `lifecycle-stage`, `company-name` and `last-activity-date`. If the contact has a `company-id`, call `hubspot-get-deals` with `company-id` and note whether any deal has a `close-date` today or later.

**Step 3: Report**

1. Grouped by HubSpot owner: contact, company, bounced email, bounce types, latest bounce date, and whether their company has an open deal. Put contacts with an open deal first.
2. Bounced addresses not found in HubSpot, as a separate list.
3. One line saying each owner should confirm or correct the address in HubSpot.

**Rules & Guidelines:**

* `constant-contact-get-campaign-bounce` is on the Constant Contact server. `hubspot-get-contacts` and `hubspot-get-deals` are on the HubSpot server.
* This prompt is read-only. Do not change any email address. Do not call `hubspot-update-contact`, `hubspot-add-contact-note`, `constant-contact-update-contact` or any other add, update or resend tool on either server.

**Validation:**

* Match email addresses case-insensitively and trimmed.
* If more than 200 bounced addresses come back, report the first 200 and say the window should be narrowed.
* Show bounce types exactly as Constant Contact returns them.
