Scope: Keep the CPU pixels (mVKCpuData), discard state machine, serial/generation, setSubImageVK, replaceVKCpuData, alpha analysis and pick mask. Drop mTexName, bindless and GL upload. The LLPixelFormat enum (components, BGR order, type) replaces GL enums in LLImageGL/setExplicitFormat/the media plugin messages, with the translation at the plugin boundary. Material store fields become VK texture indices (deletes the getBindlessHandle calls).

Prereq: B4, B5

Acceptance: Textures, media on a prim (CEF/VLC/GStreamer), UI images, picking transparent HUDs, and the "cpu tex" memory line unchanged

Risk: high (L)

Shared acceptance baseline: links; logs in under VK and renders prims/mesh/rigged/terrain/water/sky/particles; click-select object/avatar/attachment; region crossing + teleport; no GLSL Compilation Error|SIGSEGV in the log.
