[hacha]

Implemented WASD movement, Y-axis movement in UE, and direction changes while holding the right mouse button only during UnityEditor runtime.
There might be more appropriate class names available.

Pull Request Overview

This PR adds an EditorPlayerController for STYLY XR Rig that enables WASD movement and mouse-look controls specifically for Unity Editor runtime testing. The controller provides a traditional FPS-style control scheme to navigate the XR environment during development.

• Implemented WASD movement with E/Q for vertical movement
• Added right-mouse-button look controls with sensitivity settings
• Created editor-only functionality that compiles out for builds

The magic number 0.1f should be extracted to a named constant or configurable field to make the sensitivity scaling more transparent and maintainable.

Suggested change

	Vector2 mouseDelta = mouse.delta.ReadValue() * lookSensitivity * 0.1f;
	Vector2 mouseDelta = mouse.delta.ReadValue() * lookSensitivity * mouseSensitivityScale;

[Copilot]

The vertical rotation limits (-90f, 90f) should be extracted to configurable fields or constants to allow customization of the look angle constraints.

Suggested change

	rotationX = Mathf.Clamp(rotationX, -90f, 90f);
	rotationX = Mathf.Clamp(rotationX, minVerticalAngle, maxVerticalAngle);

@hacha Thank you for the implementation.

@afjk This script needs to be attached to the Rig. So we need to merge #95 first.

This PR also attaches scripts to STYLY XR Rig/_Added/XRRigManager.
