chore: update project structure and enhance plugin functionality

- Added new entries to .gitignore for database files.
- Updated go.mod and go.sum to include new indirect dependencies for database and ORM support.
- Refactored event handling to improve message reply functionality in the protocol.
- Enhanced the dispatcher to allow for better event processing and logging.
- Removed outdated plugin documentation and unnecessary files to streamline the codebase.
- Improved welcome message formatting and screenshot options for better user experience.
