Vulkan backend alongside software + OpenGL: geometry/textured-prim pipelines, GPU-authoritative VRAM image, deferred-submit + drain-at-present perf model, GPU-direct present (vk_renderer_present_vram), and a full-VRAM-pack readback path (ensure_cpu rect_adds the whole VRAM rect before pack_flush so screenshots/guest VRAM reads reflect live content, not just the incremental pack-dirty rect — readback-only, no per-frame cost). Runtime plumbing: --debug-port / --renderer / --window-title CLI overrides (multi-instance fleet), latency_ring, SPIR-V shaders + embed_spirv.py, config_loader renderer selection, debug_server screenshot wiring. All on feat/vulkan-renderer; snapshot in backup/vulkan-wip-20260617. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
