Pull request overview

This PR fixes production build issues with WalletConnect/AppKit by moving the initialization from the root app.vue component to a lazy-loaded pattern within the useAppKit composable. The changes implement SSR-safe initialization and create plain chain objects to avoid Viem Proxy serialization issues during build.

Changes:

• Removed AppKit initialization from app.vue root component
• Implemented lazy initialization in useAppKit composable with SSR guards
• Added module-level state tracking to prevent duplicate initialization
