Compare campaign effort in TickTick with Constant Contact results

**Objective:** For campaigns sent in the last `{lookback-days}` days (default 30), compare the focus time spent on their TickTick tasks with the campaign's results in Constant Contact.

**Step 1: List campaigns (Constant Contact server)**

Call `constant-contact-get-campaign` with `last-sent-date.from` set to today minus the lookback. Keep `campaign-id`, `name`, `sends`, `opens`, `clicks`, `bounces`, `opt-outs`. If none, say so and stop.

**Step 2: Find campaign tasks (TickTick server)**

For each campaign call `ticktick-get-tasks` with `title.contains` set to the campaign `name`, and `ticktick-get-completed-tasks` the same way. Keep each task `id` and `title`.

**Step 3: Add focus sessions (TickTick server)**

For each task id call `ticktick-get-focuses` with `task-id` and sum `duration-seconds`.

**Step 4: Report**

One row per campaign: name, tasks found, total focus hours, sends, open rate (opens / sends), click rate (clicks / sends), opt-outs. Rank by focus hours and note any campaign with a lot of effort and weak results, or strong results with no tracked effort. Campaigns with no task are listed separately as "no tracked effort".

**Rules & Guidelines:**

* `constant-contact-get-campaign` is on the Constant Contact server; the TickTick tools are on the TickTick server.
* Matching is by campaign name in the task title only. State this limit in the report.
* Read-only. Do not call `ticktick-add-focus-session`, `ticktick-delete-focus-session`, `ticktick-update-task` or any write tool on the Constant Contact server.

**Validation:**

* If sends is zero, show the rates as not available rather than dividing.
* Do not claim focus time caused the results; present them side by side.
