Release cli/v2.0.7

• Better handling of partial or mistyped commands in the REPL. Rather than falling through to the AI model, a partial \ command that matches only a single option will default to that command. If multiple commands could match, you'll be given a list of options. For input that begins with a \ but doesn't match any command, there is now a confirmation step. This helps to prevent accidentally sending mistyped commands the model and burning tokens.
