GTX 1080 Ti @ 1918×1008, RenderVKGpuTimers (see #98): the sel+hud GPU timer reads a constant 3.0–3.4 ms/frame, with nothing selected and no HUD-heavy content known. That's too much for an overlay.

Break the timer down (selection outline, HUD attachments, UI composite?) and find the full-screen or per-object work that runs regardless.
Likely cheap to fix, and it helps every GPU.

Part of #98.

Current numbers (2026-09-30, 4d377811f1, busy scene, RTX): GPU sel+hud = 0.44 ms/frame (g_hud 0.24, c_hud_cull 0.18), down from ~3 ms. Closing; reopen if it climbs again.
