Fixes from live-session feedback: overlay mouse can now reach the full overlay even with an off-screen oversized game window; imageOffsetX now converges/diverges the eyes in Smooth stereo mode; recenter/auto-center requests are no longer dropped while the camera path is still booting (menus/loading); HUD placement logs now name the exact gate that blocks compositing (reason=...); new once-per-session auto-align diagnostic line. 5VR-QuickStart.exe = all-in-one setup; 5VR-1.0.1.zip = raw files. 413/413 unit tests green.
