feat: GPU semi-transparency + 85 GTE library seeds + debug commands
GPU fixes: - Mono tri/quad/rect/dot/8x8/lines: route through sw_renderer with semi-transparency support (bit 25 extraction + sw_set_semi_transparency) - Add 16x16 mono sprite (0x78-0x7B) and 1x1 textured dot (0x6C-0x6F) - Add per-opcode execution counter (gpu_get_opcode_count) GTE library: batch-discovered 85 functions in BFC33000-BFC36000 including SetRotMatrix, SetTransMatrix, and full transform pipeline. Emitted: 1173 (was 1086). Seeds: 955. Zero dispatch misses. Debug commands: gpu_opcodes, gte_state, screenshot_file (BMP to disk). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
