Enhancement: Offline Mode, Cheats, Tailscale Access, and Localization

[Th3w33knd]

Summary

This PR consolidates several major enhancements to the reVCDOS project, making it more accessible, feature-rich, and easier to use for "no-code" users.

Key Features

1. Offline Mode & Asset Management

• Offline Mode: Added pixi run offline to play using only local files (strict no-network mode).
• Smart Caching: Restored and optimized caching behavior. pixi run online checks local files first, then downloads from CDN if missing.
• Fixes: Resolved directory nesting issues and added vcbr to .gitignore.

2. Cheats & "No-Code" Improvements

• Cheat Command: Added pixi run cheat which starts the server, opens the browser, and enables the cheat menu automatically.
• Cheat Menu: Press F3 to access the memory scanner and classic GTA VC cheats.

3. Remote Access (Tailscale / LAN)

• Server Binding: Changed server.py to bind to 0.0.0.0 instead of localhost, allowing connections from other devices on the network (LAN, Tailscale).
• Documentation: Added a detailed guide on how to connect remotely and handle "Secure Context" browser restrictions (using Tailscale Serve or browser flags).

4. Localization & Credits

• Translation: Fixed Russian text in the main menu (Subscribe for news and releases).
• Credits: Added a comprehensive credits section in the footer acknowledging the original authors, deobfuscator, translators, and contributors.

Documentation

• README.md: Completely overhauled with a "Quick Start" guide, download links for assets, project structure explanation, and a detailed Changelog.
