Enhance build configuration and scripts

- Updated electrobun.config.ts to include environment-based settings for stability and external dependencies.
- Refactored package.json scripts for improved build processes and streamlined commands.
- Added new build scripts for Linux and renderer, while removing the obsolete build-server script.
- Enhanced pre-build validation to ensure required files are present and added logging for better visibility.
- Updated clean-build script to remove additional artifact directories for thorough cleanup.

 ## Building
 
-- Desktop app (current platform): `bun run build:app`
-- Linux headless packages: `bun run build:linux`
+Build configuration lives in `electrobun.config.ts` and follows the [Electrobun build configuration](https://framework.blackboard.sh/electrobun/apis/cli/build-configuration/) model:
 
-Electrobun handles desktop packaging. Linux headless builds use `bun build --compile`.
+- **preBuild** — validates sources, writes build metadata, and runs the Vite renderer build
+- **postPackage** — normalizes release artifacts (DMG/PKG on macOS, MSI on Windows)
+
+Commands:
+
+- Desktop app (current platform): `bun run build:app`
+- macOS universal (arm64 + x64): `bun run build:app:mac`
+- Linux headless packages: `bun run build:linux`
+- Clean build outputs: `bun run clean`
+
+Desktop artifacts are written to `app_dist/`. Linux headless builds produce `.deb` and `.rpm` packages in the same folder.
