Tell customers their website bug is fixed

**Objective:** For tasks in the BugHerd project `{project-name}` finished in the last `{lookback-days}` days (default 14), tell the customers whose Zendesk tickets are linked to them that the problem is fixed.

How the two systems are linked: a BugHerd task created from a Zendesk ticket carries "zendesk:<ticket id>" in its external-id, and the ticket gets a private note naming the task. When a ticket is raised from a BugHerd task, the task gets a comment naming the ticket. A ticket is open when its status is new, open, pending or hold; solved and closed are finished.

**Step 1: Find finished linked tasks**

Call `bugherd-get-projects` with `name.contains` set to `{project-name}`. If nothing matches, say so and stop. If several match, list their names and project-id values and ask which one; do not guess. Then call `bugherd-get-tasks` (status done or closed) and `bugherd-get-archived-tasks` with `project-id` and `max-records` 500. Keep tasks whose external-id starts with "zendesk:" and that finished in the period (use closed, or created when closed is empty).

**Step 2: Read the tickets**

For each, call `zendesk-get-ticket` with `ticket-id`. Keep open tickets only.

**Step 3: Draft**

For each ticket, draft a short public reply in plain language: thank the requester by first name, say the problem they reported on the website (describe it in their words) has been fixed, ask them to reply if they still see it. No internal task numbers or links. Show all drafts in one table with ticket id, requester, subject and draft, and ask which to send; accept edits.

**Step 4: Send approved replies**

For each approved row, call `zendesk-update-ticket` once with `id` set to the ticket id, `comment` set to the reply, `comment-public` true and `status` solved.

**Step 5: Report**

Tickets updated, tickets skipped, and any failures with the error.

**Rules & Guidelines:**

* Tools named bugherd-... are on the bugherd MCP server; tools named zendesk-... are on the zendesk MCP server. If either set of tools is missing, say which server is not connected and stop.
* The only write tool this prompt may call is `zendesk-update-ticket`, once per approved ticket.
* Never send a reply the user has not approved, and never touch BugHerd tasks here.

**Validation:**

* If no linked ticket is still open, say so and stop.
