Support for Importing Chats Directly into Projects/Agents Based on Original Claude Structure

When importing a large number of chats from Claude (JSON export), allow TypingMind to:

Recognize the original project/agent for each chat (based on metadata or folder in Claude export)

Automatically assign imported chats to corresponding folders (projects) or agents in TypingMind

Help users maintain their original organization from Claude with minimal manual effort

This would save time for users migrating from Claude and make it much easier to get started in TypingMind.
