chore: update Amber CLI configuration and documentation

- Introduced AMBER_YML constant for configuration file path, with a TODO to move it to config/amber.yml.
- Removed legacy SentryCommand class and its options, streamlining the Sentry module to focus on file watching and process management for the Amber CLI.
- Enhanced documentation comments to clarify the purpose of the Sentry module and its functionality.
