Presentation Context Menu Extension

Build a custom context menu extension for a Slidev presentation that adds developer-friendly shortcuts when right-clicking on slides during development mode.

Requirements

Your task is to extend the Slidev context menu with custom actions that help developers work with their slides more efficiently. The context menu should include:

1. Slide Information: Add a menu item that displays an alert showing the current slide number and total slide count (e.g., "Slide 5 of 20")

2. Copy Slide Path: Add a menu item that copies the current slide's route path to the clipboard

3. Jump to First Slide: Add a menu item that navigates to the first slide in the presentation

4. Mode-Specific Display: The custom menu items should only appear in development mode, not in build/production mode

Implementation

Create a setup file that registers these custom context menu items. The setup should use the appropriate Slidev setup hook for context menu customization.
