Chat
User-facing chat loop, conversation management, and slash commands.
Lilith.Chat.cs
ChatAsync— streams a user message (optional images) and logs token usage.NewConversation/SaveConversation/LoadConversation— session persistence via Agent-Core chat history.HandleInputAsync— parses commands (exit,/new,/history, etc.) or forwards text toChatAsync.
