SwitchToVR/MR via StylyXrRig

[from2001]

This pull request refactors the way passthrough mode and XR mode switching are managed in the XR rig codebase, improving encapsulation and making the PassthroughManager methods and properties internal. The main logic for passthrough mode is now accessed through the StylyXrRig class, which delegates to its internal PassthroughManager instance. This change enhances the clarity of the public API and restricts direct access to passthrough controls.

Encapsulation and API changes:

• Made PassthroughManager.PassthroughMode property and SwitchToVR/SwitchToMR methods internal, restricting their access to within the assembly. [1] [2]

Delegation and initialization:

• Added a private PassthroughManager field to StylyXrRig and initialized it in Awake using GetComponentInChildren. [1] [2]
• Updated StylyXrRig to expose public PassthroughMode property and SwitchToVR/SwitchToMR methods, which delegate to the internal PassthroughManager if available.

Minor cleanup:

• Removed an unused variable declaration in StylyXrRig for cleaner code.

Pull Request Overview

This pull request refactors the XR rig codebase to improve encapsulation by moving passthrough mode controls from direct PassthroughManager access to delegation through StylyXrRig. The changes make PassthroughManager methods and properties internal while providing public access through StylyXrRig.

• Made PassthroughManager methods and properties internal to restrict assembly access
• Added delegation layer in StylyXrRig to provide public API for passthrough controls
• Updated component initialization to use GetComponentInChildren instead of FindFirstObjectByType
