Simply Screens 0.8.9

Fixes

• Fixed distance-dependent screen image z-fighting while keeping images visually flush with the screen surface.
• Preserved normal foreground occlusion instead of using see-through rendering.
• Preserved PNG transparency and semi-transparent blending in the custom 1.21.1 and 26.1.2 screen render paths.

Verification

• Added real framebuffer regression coverage across every supported loader/version, facing, distance, angle, occlusion, reload, and cross-chunk case.
• Added transparent and semi-transparent image coverage so alpha/blending regressions fail the visual gate.
• Negative controls reproduce the old depth conflict and foreground leakage before the fixed renderer can certify the change.
