  - keyring_token_store_go_infra (SO keychain)
  - matrix_client_init_go_infra (mautrix client)
- whoami helper to discover user_id+device_id pre-init

Frontend React+Vite+TS:
- Mantine v7 + @tabler/icons-react
- LoginScreen with 'Sign in with Matrix' button
- HomeScreen with profile card + logout
- Dark theme violet accent
