Book a Pipedrive follow-up for every Mailchimp clicker

**Objective:** Find everyone who clicked the Mailchimp campaign `{campaign-title}`, match them to Pipedrive people, and after confirmation schedule one Pipedrive follow-up activity of type `{activity-type}` (default call) for each, due in `{due-in-days}` days (default 2).

**Step 1: Find the campaign in Mailchimp**

Call `mailchimp-get-campaign` with `title` set to `{campaign-title}`. If nothing comes back, retry with `title.contains`. If more than one matches, list them with send dates and stop. Note `campaign-id` and `send-date`.

**Step 2: Get the clickers**

Call `mailchimp-get-campaign-email-activity` with `campaign-id` and `action` set to click. If the action filter returns nothing, call again without it and keep only rows whose action is click. Reduce to distinct email addresses.

**Step 3: Carry each email across to Pipedrive**

For each email, call `pipedrive-get-person` with `email`. Then:

* Found: call `pipedrive-get-activity` with `person-id` and `done` false. If the person already has an open activity, mark Skip (already has open activity).
* Not found: mark Not in Pipedrive. Do not create the person here; the campaign-responders-to-leads prompt handles that.

**Step 4: Confirm the plan**

Show a table: email, Pipedrive name, owner, open deals, planned action (Schedule, Skip, Not in Pipedrive). Ask the user to confirm before writing anything. If they do not confirm, stop.

**Step 5: Schedule, once per person**

For each Schedule row, call `pipedrive-add-activity` once with `person-id`, `type` set to the activity type, `subject` set to Follow up: clicked plus the campaign title, `due-date` set to today plus the due-in days, and a `note` listing the URLs the person clicked.

**Step 6: Confirm the result**

Call `pipedrive-get-activity` with each `person-id` and `done` false, and report which activities now exist and which failed.

**Rules & Guidelines:**

* Tools named `mailchimp-*` are on the mailchimp server and are only read here. Tools named `pipedrive-*` are on the pipedrive server.
* The only write allowed is `pipedrive-add-activity`, once per confirmed person, after Step 4. Do not call `pipedrive-add-person`, `pipedrive-add-lead`, `pipedrive-add-deal`, `pipedrive-update-person`, `pipedrive-update-deal`, `mailchimp-update-list-member`, `mailchimp-add-segment-member` or any other write tool.

**Validation:**

* Match emails case-insensitively and trim spaces.
* If the campaign has no clicks, say so and stop.
* If none of the clickers are in Pipedrive, report the list and stop without writing.
* If the activity type is not a key this account uses, call `pipedrive-get-activity-type` to show the valid keys and ask which to use.
