Closes the 0.1.5 performance task. Same route and preset as 0.1.0 (packaged
Development, Epic scalability, TSR, VSync off, no frame generation, 2560x1440):
0.1.0 2.42 ms (414 fps) p99 3.01
0.1.5 (kit) 2.76 ms (363 fps) p99 3.64
The 625 kit actors and 8 generated textures cost about 12% of frame time and still
leave roughly six times the 60 fps floor. Frame-time series committed at
Docs/perf/0.1.5-kit-walk-frametimes.csv; comparison table added to
Docs/release-checks.md.
Records the measurement trap once more: runs showing ~105 fps were two overlapping
game instances, not the build - 363 fps reproduced twice on a clean single instance.
