Compare weekly call hours with focus time

**Objective:** For the Chorus user with email `{user-email}`, compare time on recorded conversations with TickTick focus time and completed tasks between `{from-date}` and `{to-date}`. Read only.

**Step 1: Calls (Chorus server)**

Call `chorus-get-engagements` with `user-email`, `date.from` and `date.to`. Sum `duration` and count conversations per week.

**Step 2: Focus and completed work (TickTick server)**

Call `ticktick-get-focuses` with `start-time.from` and `start-time.to`; sum `duration-seconds` per week. Call `ticktick-get-completed-tasks` with `completed-time.from` and `completed-time.to`; count per week.

**Step 3: Report**

A weekly table: calls, call hours, focus hours, tasks completed. Then two or three plain observations (for example weeks with heavy calls and little focus time). Note that the TickTick account is the one connected to that server and may not belong to the same person; state this assumption.

**Rules & Guidelines:**

* `chorus-get-engagements` is Chorus; `ticktick-get-focuses` and `ticktick-get-completed-tasks` are TickTick.
* Do not call any write tool on either server, including `ticktick-add-focus-session` and `ticktick-delete-focus-session`.

**Validation:**

* If either side returns nothing, report that side as empty rather than as zero activity.
* If duration units are unclear, state the unit you assumed.
