Lands the non-networked Phase 0 tasks from multiplayer-todo.md (ship/camera/ arena refactors, sim constants, background FPS handling) plus a first pass at exposing graphics/performance settings (presets, resolution scaling, vsync, FPS cap, perf overlay) and a GPU profiling harness for the real-hardware follow-up in task 0.15b.
