feat: add command palette and dashboard view components

- Introduced a command palette for enhanced navigation and command execution.
- Added a new dashboard view with project management features, including project cards and an empty state for new users.
- Updated routing to include the new dashboard view and integrated it with the existing layout.
- Enhanced the app store to manage pinned projects and GitHub cache for issues and pull requests.

These changes improve user experience by streamlining project management and navigation within the application.
