Add README, CLAUDE.md, INSTRUCTIONS.md, and CI workflow
- README.md: feature list, stack, project structure, deferred items
- CLAUDE.md: architecture, conventions, route map, CSS variable system,
EventSub subscription table, data model, custom event names
- INSTRUCTIONS.md: step-by-step initial deploy guide (Twitch app
registration through OBS setup and custom CSS/JS), plus git workflow,
first push, GitHub Actions, branching, and update procedure
- .github/workflows/ci.yml: syntax check and import check on every push
