Tell Salesforce owners which contacts opted out or bounced

**Objective:** List every Salesforce contact or lead who unsubscribed from, or had a bounce on, Constant Contact email in the last `{lookback-days}` days (default 30), so the record owner knows the address is opted out or bad.

**Step 1: Read opt-outs and bounces in Constant Contact**

With `created-date.from` set to today minus the lookback window, call `constant-contact-get-campaign-unsubscribe` and `constant-contact-get-campaign-bounce`. Reduce to distinct `email-address` values, keeping for each the latest event, its date, the unsubscribe `reason` or the `bounce-type`, and the `campaign-id`.

**Step 2: Match each address in Salesforce**

For each email, call `salesforce-get-contact` with `email`. If nothing comes back, call `salesforce-get-lead` with `email`. Addresses that match neither are out of scope; count them but do not list them.

**Step 3: Add commercial context**

For each matched contact, call `salesforce-get-opportunity` with its `account-id` and `closed` = false, and note whether the account has open opportunities.

**Step 4: Report**

Two tables, unsubscribes and bounces, each with: email, Salesforce record type, name, account or company, owner, event date, reason or bounce type, open opportunities (yes/no). Sort each by owner. Flag rows with open opportunities first. End with counts: events read, matched in Salesforce, not in Salesforce.

**Rules & Guidelines:**

* Tools named `constant-contact-*` are on the constant-contact server; tools named `salesforce-*` are on the salesforce server.
* This prompt is read-only. Do NOT call `salesforce-update-contact`, `salesforce-update-lead`, `salesforce-add-task`, `constant-contact-update-contact` or any other add or update tool. An unsubscribe is a consent signal; do not try to change it.

**Validation:**

* Compare email addresses case-insensitively and ignore surrounding spaces.
* If there are no unsubscribes or bounces in the window, say so and stop.
* If a bounce type looks temporary (a soft or mailbox-full bounce), label it as such rather than calling the address bad.
