Clean gutters and check downspouts

## Context
Add a reminder to clean gutters and confirm the downspouts drain away from the house.

## Why it matters
Clogged gutters can overflow and push water toward the foundation, so this is a simple maintenance task that helps prevent avoidable water damage.

## Proposed next step
- Schedule a gutter cleanup reminder.
- Check that downspouts are clear and directing water away from the house.
- Recheck after major storms or during seasonal leaf drop.

Start by locating the repository's existing reminder or maintenance automation entry points and compare their format. Add the gutter and downspout reminder with seasonal leaf-drop and post-storm follow-ups, then verify that the reminder appears and behaves as intended.
