fix: add 404 page and reject unknown sub-paths under /world/

Adds a custom 404.html page and client-side path validation in world/index.html so that unknown sub-paths like /world/api or /world/nonexistent redirect to the 404 page instead of silently loading the Workshop SPA. Fixes #8 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
