Pull Request Overview

This PR migrates Castroix from a Python/Tkinter application to a modern Node.js/Electron application with an Apple TV-inspired UI. The migration introduces embedded browser functionality, secure credential storage, and enhanced keyboard navigation while maintaining backward compatibility with the existing configuration format.

Key Changes

Complete Electron implementation with main process, preload bridge, and renderer process
Apple TV-like UI with smooth animations and focus-based navigation
Secure credential management using electron-store with encryption
Embedded browser functionality via BrowserView for in-app streaming

This requirement is misleading. The Electron edition doesn't require Python for its core functionality. Python is only needed if users want to run the Python edition alongside or run Python-based tests. This should be clarified as optional or separated into a different section.

Commands from the configuration file are executed directly without validation or sanitization. This could allow arbitrary command execution if the config file is modified maliciously. Consider implementing command validation, using a whitelist of allowed commands, or at minimum warning users about the security implications.

The value 400 is a magic number that should be extracted to a named constant. This value relates to the CSS minmax(300px, 1fr) grid setting and should be documented or calculated based on actual card width to maintain consistency if the grid layout changes.
