Scope: the !gWindowUseVulkan branches, createSharedContext, the swapBuffers GL arm, SDL_GL_*; then delete the gWindowUseVulkan flag itself (every site becomes unconditional)

Prereq: D2 (or earlier for just the window file)

Acceptance: window create, resize, fullscreen and vsync all work

Risk: low

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.

Status check (verification sweep): partly done. e05771cdf6 (v1.0.0-beta.1) deleted the Win32/macOS/Mesa window backends and the GL context + shared-context API (createSharedContext: 0 refs). Remaining: gWindowUseVulkan is still there (11 refs in 4 files), and SDL_GL_* calls remain (4 lines in 2 files).

Verified against forgejo/main: PARTIAL, leaving open. Done: llwindowsdl.cpp has no SDL_GL_*, createSharedContext, GL swapBuffers arm or gWindowUseVulkan branches; window create/resize/fullscreen/vsync verified on 1.2.0. Remaining: the flag itself survives as gWindowUseVulkanUI (llappviewer.cpp:389 definition, :7311 set to true; only comments read it at :4076,:6503) and should be deleted.

Pushed to main at 07c8a3ac73. GL context code removed from llwindowsdl. To test: Linux and Windows startup.
