feat: add cs-dust2 React case with two model takes + react kind support

New case cs-dust2 (kind:react): a from-scratch React + three.js 5v5 Dust2 FPS.
Two takes registered: Claude Fable 5 / Claude Code / High (with a hand fix for a
64Hz fixed-step firing bug on high-refresh displays) and Claude Opus 4.8 /
Claude Code / Max (dust2-arena, one-shot). React cases commit source only; the
single file is built from source at deploy time. validate-data.ts now accepts a
React project directory as the declared artifact. AGENTS.md rewritten
English-only with React-case, bare-harness (no skills/plugins) and
artifact-anonymity rules.

One firing bug was fixed by hand: the simulation advances in fixed 64Hz steps, and on a high-refresh display (render fps above 64) a frame may run zero fixed steps, so the original per-frame assign-and-clear of edge-triggered inputs like fireTap could swallow a click on that frame and drop the shot; the fix latches those inputs with || until a fixed step consumes them (src/game/engine.ts), making firing refresh-rate-independent."
