See your week ahead: meetings and deadlines in one view

**Objective:** Build a week-ahead view for the next `{days-ahead}` days (default 7) that puts scheduled Granola meetings alongside TickTick tasks due and countdowns, optionally limited to the TickTick project `{project-name}`. Read-only.

**Step 1: Meetings (Granola)**

Call `granola-get-note` with `scheduled-start.from` set to now and `scheduled-start.to` set to now plus `{days-ahead}` days (7 if empty). Record title, scheduled-start, scheduled-end and organiser.

**Step 2: Deadlines (TickTick)**

Call `ticktick-get-tasks` with `due-date.from` set to now, `due-date.to` set to the end of the window, open status, and `project-name` set to `{project-name}` when given. Also call `ticktick-get-countdowns` with `date.from` and `date.to` for the same window, and call `ticktick-get-tasks` again with `due-date.to` set to now for overdue open tasks.

**Step 3: Report**

For each day: meetings (time, title), tasks due (title, priority, project-name), countdowns. Flag days where meetings take more than 4 hours and tasks are due, and name the overdue tasks with how many days late. Finish with the three days that look hardest and why.

**Rules & Guidelines:**

* `granola-get-note` is on the Granola server; `ticktick-get-tasks` and `ticktick-get-countdowns` are on the TickTick server.
* Read-only. Do not call `ticktick-update-task`, `ticktick-batch-tasks`, `ticktick-complete-task` or any other TickTick write tool, and do not reschedule anything.

**Validation:**

* If there are no meetings, show deadlines only and say so.
* If there are no deadlines, show meetings only and say so.
* Treat meetings with no `scheduled-end` as one hour and mark them as estimated.
