Add 46 seeds for the libgte helper functions at BFC34E00-BFC36D00. These wrap individual GTE operations (RTPS, RTPT, NCLIP, MVMVA, etc.) and were never discovered because they're called via JALR function pointers, not direct JAL. Coverage: 52→114 gte_execute, 166→429 LWC2/SWC2. Emitted functions: 1178→1214. Seeds: 960→1006. Fix DuckStation oracle VRAM readback by setting UseSoftwareRendererForReadbacks=true in settings.ini. Add debug/analysis tools: GTE audit, VRAM stitching, rapid polling, GPU info, divergence comparison, jump table dumps. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
