Build AionUi from source using bun for dependency fetching and
electron-vite for TypeScript compilation. Native addons
(better-sqlite3, sharp) are compiled against nixpkgs node-gyp.
The package uses a fixed-output derivation for bun install,
electron-vite for the build, and wraps the result with nixpkgs
electron for a fully self-contained runtime.
Also includes desktop entry and icon generation.
