Leo 80002ea195 Prioritize global config over local .env file

Check ~/.config/prompt/config and ~/.prompt.env before .env in current
directory. This prevents issues when running prompt in project directories
that have their own .env files for other purposes.

Setup your config:

# Create the config directory
mkdir -p ~/.config/prompt

# Create config file

EOF

prompt "Hello, how are you?"

This will:

Enter an interactive chat mode where you can continue the conversation

Type exit or quit to end the conversation.

Examples

# Ask a quick question
prompt "What is the capital of France?"
