Split vulkan_window.cpp by responsibility and render() into phases

Browse Source

VulkanWindow's 3000-line TU becomes sdl_window.cpp (window, events,
cursor, screenshot BMP), vk_device.cpp (device, swapchain, MSAA,
framebuffers), vk_pipelines.cpp (render passes, pipelines),
vk_resources.cpp (buffers, render targets, geometry), vk_textures.cpp
(textures, samplers, descriptors), vk_frame.cpp (render) and
ui_batches.cpp; vulkan_window.cpp keeps construction and timing stats.
Function bodies move verbatim.

render() now reads fence/acquire -> prepare_draws -> prepare_ui ->
write_draw_states -> record_passes -> record_readbacks -> submit ->
finish_readbacks -> present, with FrameDraws / Readback carrying the
locals that used to live across 500 lines.

Verified: login-screen screenshot byte-identical to HEAD; game-world
draw/vertex/index/UI counts identical; ctest, port_gate macos+android,
Android build pass.
