Fix the BugHerd bugs that cost support the most

**Objective:** Rank the open bugs in the BugHerd project `{project-name}` by the support load they caused in Zendesk over the last `{lookback-days}` days (default 30).

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.

**Step 1: Read the open bugs**

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` with `project-id` and `max-records` 500. Drop done and closed tasks.

**Step 2: Count tickets per bug**

* Linked: a task with external-id "zendesk:<id>" counts that ticket.
* Related: for each critical or important task, pick two or three distinctive words from its title and call `zendesk-get-ticket` with `subject.contains` for each and `created.from` set to the start of the period. Count tickets that clearly describe the same problem; say these are matched by judgment.
* For counted tickets, also note the satisfaction score when there is one (`zendesk-get-satisfaction-rating` with `ticket-id`).

**Step 3: Report**

A table ordered by ticket count: task number, title, severity, linked tickets, related tickets, bad satisfaction ratings, oldest ticket. Then the three fixes that would save support the most, one sentence each.

**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.
* This prompt is read-only. Do not call any BugHerd write tool (`bugherd-add-task`, `bugherd-add-feedback`, `bugherd-update-task`, `bugherd-move-task`, `bugherd-add-comment`, `bugherd-add-attachment-from-url`, `bugherd-add-project`, `bugherd-update-project`, `bugherd-add-project-member`, `bugherd-add-guest-to-project`) or any Zendesk write tool (`zendesk-add-ticket`, `zendesk-update-ticket`, `zendesk-add-ticket-comment`, `zendesk-make-ticket-comment-private`, `zendesk-add-user`, `zendesk-update-user`, `zendesk-add-organization`, `zendesk-update-organization`, `zendesk-add-organization-member`, `zendesk-add-group`, `zendesk-update-group`, `zendesk-add-group-member`).

**Validation:**

* If no bug has any ticket, say so: support is not seeing these bugs.
