Boot

Startup and readiness for the Lilith chat session.

Lilith.Boot.cs

• BootAsync — initializes Ollama, prints the console banner, runs the opening greeting, and validates chat history.
• GreetAsync — sends the initial “greet the user” prompt through the chat pipeline.
• EnsureChatReadiness — confirms the Ollama client, system message, and context window are ready before user input.
