feat: enhance Electron build process and server preparation

- Added new build scripts for Electron targeting Windows, macOS, and Linux.
- Updated the main build script to include server preparation steps.
- Introduced a new script to prepare the server for bundling with Electron, including cleaning previous builds and installing production dependencies.
- Modified the Electron main process to verify server file existence and improved error handling.
- Updated .gitignore to exclude the new server-bundle directory.
