fix: set isAnswerOnly to false to actually implement changes

Change isAnswerOnly from true to false in auggie.prompt() call.
When isAnswerOnly is true, Auggie only provides a text description
of what it would do without actually making file changes.

With isAnswerOnly: false, Auggie will:
- Actually edit the files
- Make the requested changes
- Allow git to detect and commit the changes
