Yes chef. Right away chef.

Implements the RecentActivity component on the dashboard per issue #2.

Changes:

• Adds Notification type to src/types/index.ts
• Implements RecentActivity component in src/components/dashboard/recent-activity.tsx
• Fetches from GET /api/notifications?recipient=<connected_wallet> using React Query
• Renders scrollable feed with icons for all 4 activity types (contributions, loans, votes, distributions)
• Shows relative timestamps via date-fns formatDistanceToNow
• Includes subtle separator lines between items
• Handles unconnected wallet state with "Connect your wallet to see activity"
• Shows empty state when no notifications exist
• "Mark all read" button calls PATCH /api/notifications/:id/read for unread items
• Uses mock data fallback with clear TODO: connect to API comments while backend is being built

No TypeScript errors in modified files.
