Add vscode console postMessage to an env variable

[lascott]

The request is to expose the console messages to an env variable.
As I learn about improving my interactions, having the logs of prompts and responses would be a great thing. I created a bash script to grab the ${CHAT_CONTENT}, a mythical environment variable for the vscode console messages. With this, date and timestamped logs could be stored and analyzed.

# Function to extract chat content based on options
extract_chat_content() {
    local temp_file="$1"
    local head_lines="$2"
    local tail_lines="$3"
    local use_all="$4"
    
    if [ "$use_all" = true ]; then
        echo "$CHAT_CONTENT" > "$temp_file"
    elif [ -n "$tail_lines" ]; then
        echo "$CHAT_CONTENT" | tail -n "$tail_lines" > "$temp_file"
    else
        echo "$CHAT_CONTENT" | head -n "$head_lines" > "$temp_file"
    fi
}
