Estimated code review effort

🎯 4 (Complex) | ⏱️ ~60 minutes

Key areas requiring extra attention:

BotManager service (backend/app/services/bot_manager.py): Thread-safe singleton with background health monitoring, crash detection, auto-restart logic with backoff, and database state management—verify thread safety, backoff policy correctness, and edge cases in crash recovery.
ProcessManager (backend/app/services/process_manager.py): Subprocess lifecycle management, output streaming to logs, resource usage tracking via psutil—validate subprocess creation, signal handling, log file I/O, and cleanup guarantees.
WebSocket handlers (backend/app/routers/websocket.py): Active connection tracking, real-time streaming, connection cleanup—check for connection leaks, proper error handling, and graceful disconnection.
Authentication flow (backend/app/routers/auth.py): JWT token creation/verification, password hashing, user validation—confirm token expiry logic, refresh token handling, and password security practices.
Database initialization (backend/app/database.py): Conditional SQLite setup, lazy model imports for metadata creation—verify import order and transaction safety.
Frontend hooks & API layer: Ensure proper React Query integration, error boundaries, and WebSocket lifecycle management in real-time features.

Poem

🐰 A dashboard born, with bots to manage,
Telegram whispers, Discord in passage,
WebSocket streams dance, stats take flight,
FastAPI frameworks and Next.js delight,
From seed to scaffold, the journey's bright! 🌟
