Update logging and enhance .gitignore for Atlas directory

- Introduced a logging system using `tracing` and related crates to improve log management and output formatting.
- Updated `.gitignore` to include the `.atlas/` directory, ensuring that log files and other generated content are not tracked by Git.
- Enhanced project templates to include the new `.gitignore` settings for Atlas in various project types.

These changes aim to improve logging capabilities and maintain a cleaner repository by ignoring unnecessary files.
