Recent Items: show last opened tasks/projects #25
Description
Summary
Show recently viewed tasks and projects (last 3–5) in the sidebar for quick access.
Current behavior
- Sidebar is static with links in src/components/dashboard/Sidebar.tsx.
- Task modal opens on selection in the kanban board (src/components/ui/kanban-board/task-card.tsx -> tasks-client.tsx).
Target behavior
- Track recently opened tasks and projects.
- Display a compact list in the sidebar (collapsed state should show icons only).
- Persist the list in localStorage, with dedupe and recency updates.
Scope
- Add a recents store and update hooks on task/project open.
- Sidebar UI block for recents.
- Limits, dedupe, and clear action.
Acceptance criteria
- Last 3–5 items persist across reloads.
- Clicking a recent item opens the task modal or project page.
- Recents update on every open and do not include duplicates.
