chore: remove remotion and @remotion/player from dependencies

- Removed 'remotion' and '@remotion/player' from package.json
- Deleted Root.tsx (SSR composition registry, no longer needed for frontend)
- Updated build scripts to skip remotion:bundle step
- Kept @remotion/bundler and @remotion/renderer for server-side (Phase 4)
- Verified: electron-vite build passes cleanly
