Remove the sample project: LittleSim is the engine showcase now

CI / build-test (push) Failing after 1m4s
The MrGameEng.Sample demo game is deleted along with its assets; the LittleSim god-sim (which vendors this engine as a submodule) takes over as the living showcase where every engine feature is demonstrated. CLAUDE.md, README and docs updated; the demonstration rule now points to LittleSim, and the stress-scene perf figure is kept as a historical reference measurement.
