v3.0 — Clean Build

Clean Build

Matches UEVR v3.0 and VRto3D v3.0. Clean codebase with standardized UE3D naming.

What's Included

• LeiaSR SDK 1.34.5 with factory weavers (DX11 + DX12)
• getPredictedEyePositions() for per-frame Leia eye tracking
• UE3D protocol v4.0 shared memory bridge (writes eye positions for UEVR LookAround)
• IPD-based face-lost detection with grace period
• SR::Display query for physical display dimensions
• 64-bit only (Leia SDK 1.34.5+ dropped 32-bit)

What Changed from v2.0
