I've integrated the Rust backend for process management and API proxy-

[AlphaEcho11]

This was a significant architectural change where I moved core functionality to the Rust backend of the Tauri application.

Here are the key changes:

• Process Management: The Rust backend now launches and manages an external text-generation-webui process. You can configure the path to this executable via a new settings.json file. The backend ensures the process is terminated gracefully when the application exits.
• API Proxy: I added a new proxy_request command in Rust. This command forwards API calls from the frontend to the text-generation-webui service, centralizing communication and hardening the application.
• Frontend Refactoring: The KoboldAI chat feature in the frontend has been updated to use the new Rust proxy instead of making direct fetch calls.
• Configuration: A settings.json file has been added to the root of the project to allow you to specify the path to your text-generation-webui executable.
• Documentation: I also added a DEPLOYMENT.md guide to explain how you can set up and run the new version of the application.

Summary by CodeRabbit

• New Features

  • Local desktop proxy for streamed chat responses and a blocking fallback for vision replies.
  • Quit confirmation flow for safer app exit.

• Documentation

  • Added Deployment Guide for running the Rust-powered backend locally (setup, config, build, run).

• Chores

  • Tauri/tooling upgraded and packaging/config keys reorganized; included app resources and tightened shell permissions.

• Bug Fixes

  • Improved startup configuration validation, sidecar lifecycle management, path validation, and user-facing error dialogs.

Walkthrough

Adds a local Deployment guide and default settings; upgrades Tauri to 2.0.0-beta and adds reqwest/futures-util; rewrites the Tauri backend to manage a sidecar, validate/sanitize proxy paths, and add streaming/blocking proxy commands; updates tauri config and resources; frontend adds quit confirmation and proxies OpenAI streaming/blocking through Tauri.

Changes

Cohort / File(s)	Summary of Changes
Documentation DEPLOYMENT.md	New deployment guide for running Amica locally: prerequisites, install/config/build/run steps, OS config locations, settings.json format, artifacts, and runtime notes.
Tauri Cargo / Dependencies src-tauri/Cargo.toml	Upgraded tauri to 2.0.0-beta.21 (removed shell-open feature); added reqwest = { version = "0.12.5", default-features = false, features = ["json","rustls-tls"] } and futures-util = "0.3.30".
Tauri Config & Resources src-tauri/tauri.conf.json, src-tauri/resources/settings.json	Restructured tauri config (keys renamed/moved: devPath→devUrl, distDir→frontendDist, tauri/tauri.bundle → top-level bundle, added root-level version/identifier); added resources entry and src-tauri/resources/settings.json with {"text_generation_webui_path": ""}.
Tauri Backend Core src-tauri/src/main.rs	Major rewrite: adds AppState (sidecar child + termination flag), Settings struct and settings load from OS config or bundled resource, executable path validation/sanitization, allowlisted proxy paths, spawning/forwarding sidecar stdout, graceful shutdown, and new commands: proxy_request_streaming, proxy_request_blocking, quit_app; updates close_splashscreen to a tauri command. Implements streaming primitives that POST to localhost and emit stream-chunk/stream-end/stream-error events.
Frontend App Lifecycle src/pages/_app.tsx	Adds client-side listener for confirm-close that prompts the user and invokes quit_app on confirmation; the listener is cleaned up on unmount.
Frontend Chat Proxy Refactor src/features/chat/openAiChat.ts	Replaces direct frontend OpenAI HTTP streaming with Tauri-backed proxy streaming via proxy_request_streaming and event listeners; blocking requests use proxy_request_blocking. Adds stream cleanup, API key validation, updated types/signatures (vision chat now returns Promise<string>).
Node Package Config package.json	Upgraded Tauri JS packages to pinned 2.0.0-beta.x devDependencies: @tauri-apps/api and @tauri-apps/cli.

Poem

I nibble bytes beneath the moon,
A sidecar hums a steady tune.
Chunks hop out in tidy streams,
Settings snug in config dreams.
Build and run — the rabbit beams. 🥕✨
