hosseinfallah-h/taskverse ? reverse-engineered prompt

Build me a Persian first task manager called TaskVerse, with a polished Flutter mobile app and a FastAPI backend. It should work offline, save data locally, then sync when the server is available, and it should feel premium and simple for everyday use.

I want users to be able to sign in with OTP, create and edit tasks, organize them in a clean modular way, and see helpful stats and progress over time. Please also include the Bale bot side so it can send a morning brief around 7AM, share a recap, and let me add tasks by voice or chat. Use PostgreSQL and Redis on the backend, keep everything self hosted, and avoid any foreign telemetry. If you need to check current docs for Flutter or FastAPI details, go ahead and look them up online. Please keep the codebase organized so each feature lives in its own folder on both the app and backend.
