Port the OpenAI Codex develop-web-game skill (Playwright-based game dev
loop) into skills/develop-web-game/ with paths adapted for Arc's
workspace-relative skill discovery. Add a web-game-demo workflow that
verifies the skill and its asset files (playwright client script,
action payloads JSON) are properly discovered and accessible in a
Daytona sandbox.
