optimize-tauri-backend — Tauri 后端优化

Use this skill to turn a growing Tauri backend into a smaller, more stable, more pleasant development surface. The goal is not magical Rust HMR. The goal is to reduce how often Rust changes are needed, make Rust restarts less disruptive, and keep the Tauri command boundary small, typed, and auditable.

When to Use

• The user is developing with pnpm tauri dev / npm run tauri dev and Rust file changes keep closing and reopening the app.
• src-tauri/src/lib.rs has become a God file.
• The app exposes 100+ or 200+ #[tauri::command] functions.
• Frontend code scatters raw invoke("command_name") strings across many components.
• Long-running invoke / Channel calls cause stale callback warnings after reload or HMR.
• The user wants backend modularization, command consolidation, better dev scripts, or restart-state recovery.
