Niyra voice system — every message in her voice
Brand-wide voice catalog. NiyraError envelope on the backend (models.SendNiyraError), NiyraToast/NiyraMessage on the frontend with orb + label identity. ESLint rule blocks raw sonner toast calls.
No more "Error: ECONNREFUSED" leaking through. Every system message — errors, toasts, validation, empty states — speaks as Niyra. See `docs/niyra-voice-guide.md`.
