v0.2.0

List of changes:

• Don't send the folder context by default. Now you must use -ctx flag to enable it.
• Use dolphin-mistral:latest as default ollama model. It gives much better results.
• Add check for model; show error if it does not exist or is not yet pulled.
• Add check for ollama version; it must be at least 0.1.14 for maestro to work.
• Other minor improvements.
