- Lazy-import CreateRoomForm/CreateSpaceForm in CreateRoom.tsx and Create.tsx
so create-room and create-space get their own chunks; eliminates
INEFFECTIVE_DYNAMIC_IMPORT warnings
- Add RouteError component wired to root route errorElement so crashes show
a reload button instead of React Router dev screen
- ci.yml: use secrets.SENTRY_AUTH_TOKEN so source maps upload on CI builds
