#1720 was merged at a259978, a one-step commit on its branch where gpu/vk/vk_replay.cpp was briefly back at main's version (to get past a conflict while merging main in; the next commit was to re-apply it). So main now has vk_framegen.cpp calling present_commit and using present_defer_into, which nothing defines (an unresolved link on every build), and tests/test_present_ahead.py and tests/test_present_semaphores.py fail.

This puts back the missing 24 lines in gpu/vk/vk_replay.cpp on top of main 51de681, unchanged from the reviewed version: present_defer_into, present_commit, and present_image's end as present_out, after main's device-loss check on the copy's submit.

Validation:

• The same 24 lines as the version reviewed and tested in fix(vk): submit a 2x set's copies together so its presents keep their times #1720 (there resolved against b2ed731 and run in game).
• 27 related checks pass on this branch with LLVM-MinGW on Windows (present ahead, present semaphores, framegen gate / auto / preset, frame wait bounds, device lost exit, capture, flash sampling, framelog, Reflex swapchain lifetime, swapchain compat and colorspace, parallel). On main 51de681, test_present_ahead.py and test_present_semaphores.py fail.

Sorry for the trouble: the merge landed between the two commits.

Closing in favour of #1858, which puts back the same 24 lines.
