Add new Node.js SDK with reactive updates for Pantry

[DinoscapeProgramming]

This SDK improves the developer experience when interacting with Pantry's API by offering a lightweight, reactive, and intuitive interface for working with baskets. It supports automatic syncing of local state with Pantry and is designed to feel natural for modern JavaScript developers.

• Created a new Node.js SDK: PantryJS
• Provides reactive basket objects with auto-update on mutation
• Uses bent for HTTP requests (lightweight and Promise-based)
• Clean syntax: (await pantry.store).value = "hello" auto-syncs to Pantry
• Designed to work with async updates while keeping a clean API
• Packaged and published on npm under pantry.js
