[Prototype] Game Controller Support Testing for Rein

[anshulchikhale30-p]

Context

Moving away from NutJS in favor of virtual input devices. Rein is a cross-platform LAN-based remote input controller that could replace NutJS, as it doesn't scale as well as virtual input devices.

Proposed Solution

Create a prototype with available virtual input libs maybe in rust and test the controller input functionality on supported games.

The prototype will:

1. Read gamepad/controller input using a virtual input module
2. Integrate with Rein's modules to send input commands
3. Test on games with controller support
4. Document the implementation approach for others to contribute

Future: Wrap Rust modules with Node.js bindings for easier integration.

Alternatives Considered

1. Continue using NutJS - Not viable, library is less actively maintained
2. Pure Node.js solution - Limited to mouse/keyboard, no controller support
3. Use existing game input libraries alone - Lacks the LAN-based distribution that Rein provides

Rein provides the best balance of active maintenance + cross-platform support + network capability.

Working on this now. Starting with environment setup and prototype development. @imxade
