Refactor Mattermost and Slack integration workflows to remove legacy Fidelity variables, streamline command execution, and enhance documentation for project profiles. Update scripts and README files to reflect changes in directory structure and configuration precedence, ensuring a consistent approach to project knowledge management across profiles. Improve error handling and validation in profile creation and doctor commands, and enhance test coverage for profile-related functionalities.
