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>

/* Textured primitives. Per-prim texture state (texpage, clut, depth, raw, uv
|
|
* limits) rides in FLAT vertex attributes so consecutive prims with the same
|
|
* blend/mask/texture-window/filter coalesce into one draw (see flush_tex_batch).
|
|
* The push-constant block carries the vertex transform (u_shift/u_xoff/u_xhalf)
|
|
* and the fragment batch keys (semipass/maskset/filter/twin). Ported from the
|
|
* GL backend's TEX_VS. */
