Implement True Query Concurrency with Multi-Threaded Chat UI - #453

User description

Implemented true query concurrency by introducing a multi-threaded chat interface. The system now supports multiple independent conversation threads within a single session, each with its own isolated context and map state. The backend submission logic has been updated to be non-blocking, allowing users to interact with other threads while AI processing occurs in the background. State persistence has been refactored to save each thread as a separate chat record in the database.
