Tell Pipedrive reps when email no longer reaches a prospect

**Objective:** Find the Constant Contact unsubscribes and bounces from the last `{lookback-days}` days (default 30) and log each one as a note on the matching Pipedrive person, so sales sees that email is no longer reaching them. Include bounces unless `{include-bounces}` is no (default yes). Write nothing until the user confirms the plan.

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

With `created-date.from` set to today minus `{lookback-days}` days (default 30):

* Call `constant-contact-get-campaign-unsubscribe`.
* Unless `{include-bounces}` is no, call `constant-contact-get-campaign-bounce`.

Group by `email-address` and keep the latest event of each kind, with its date, reason or bounce-type, and `campaign-id`. Call `constant-contact-get-campaign` with each distinct `campaign-id` to get the campaign name.

**Step 2: Match in Pipedrive**

For each email, call `pipedrive-get-person` with `email`. If nobody is found, list the email as "not in Pipedrive" and move on.

**Step 3: Skip what is already logged (Pipedrive)**

For each matched person, call `pipedrive-get-note` with `person-id` and `note.contains` set to Constant Contact. If a note already records the same event, skip the person.

**Step 4: Confirm the plan**

Show a table: person, email, event (unsubscribed or bounced), date, campaign, reason. The note text is "Constant Contact: <unsubscribed from | email bounced on> <campaign> on <date>. <reason or bounce type>." Ask the user to confirm. Do not continue without an explicit yes.

**Step 5: Write the notes (Pipedrive)**

For each confirmed row, call `pipedrive-add-note` once with `person-id` and `content`.

**Step 6: Confirm**

Call `pipedrive-get-note` with each `person-id` and report what was written and any call that failed.

**Rules & Guidelines:**

* `constant-contact-get-campaign-unsubscribe`, `constant-contact-get-campaign-bounce` and `constant-contact-get-campaign` are on the constant-contact server. The `pipedrive-*` tools are on the pipedrive server.
* The only tool allowed to write is `pipedrive-add-note`, after Step 4 is confirmed. Do NOT call `pipedrive-update-person` (passing an email replaces all of the person's emails), and do NOT call `constant-contact-update-contact` or any other Constant Contact add or update tool.

**Validation:**

* If there are no unsubscribes or bounces in the window, say so and stop.
* Write at most one note per person per run, combining both events if a person has both.
