Migrate Desktop Frontend to Svelte 5 and Implement Backend Connectivity

[iberi22]

This submission migrates the entire desktop application frontend from Svelte 4 to Svelte 5.

Key changes include:

• Refactored state management to use Svelte 5 runes ($state, $derived, $props, $bindable, $effect), providing a more robust and granular reactivity model.
• Migrated all event listeners to the standard HTML attribute syntax (e.g., onclick instead of on:click), aligning with Svelte 5's simplified event handling.
• Replaced the legacy createEventDispatcher in the Dojo component with a modern callback prop pattern.
• Activated and fixed backend integration by uncommenting and correcting Tauri invoke calls in ModelManager.svelte (download/load models), PermissionGuard.svelte (request permissions), and NodeInfoPanel.svelte (retrieve node info). Parameter names were aligned with the Rust backend's snake_case signatures.
• Verified syntax and type correctness via npm run check and confirmed the production build with npm run build.
• Updated .gitcore/features.json to reflect the completed status of the Svelte 5 Frontend feature.

Fixes #681

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly upgrades the desktop application's frontend by migrating it to Svelte 5. This migration involves a comprehensive refactoring of reactivity patterns and event handling to leverage Svelte 5's new runes and simplified syntax. Additionally, it re-establishes and corrects the application's connectivity with the Rust backend via Tauri invoke calls, ensuring core functionalities like model management, permission requests, and node information retrieval are fully operational. The changes enhance the frontend's performance and maintainability while ensuring seamless interaction with the underlying system services.

Highlights

• Svelte 5 Migration: The entire desktop application frontend has been migrated from Svelte 4 to Svelte 5, adopting the new reactivity model and syntax.
• State Management Refactoring: State management has been refactored to utilize Svelte 5 runes, including $state, $derived, $props, $bindable, and $effect, for a more robust and granular reactivity.
• Event Listener Update: All event listeners have been migrated to the standard HTML attribute syntax (e.g., onclick instead of on:click), aligning with Svelte 5's simplified event handling.
• Backend Integration Activation: Backend integration has been activated and fixed by uncommenting and correcting Tauri invoke calls in ModelManager.svelte, PermissionGuard.svelte, and NodeInfoPanel.svelte. Parameter names were aligned with the Rust backend's snake_case signatures.
• Component API Modernization: The legacy createEventDispatcher in the Dojo component was replaced with a modern callback prop pattern.
• Feature Flag Update: The .gitcore/features.json file was updated to mark the 'Svelte 5 Frontend' feature as completed.
