Refactor command execution and security handling

- Removed security warning detection from CommandExecution component and related tests.
- Simplified command parsing logic by consolidating command extraction and validation.
- Updated command pattern extraction to handle duplicate patterns gracefully.
- Enhanced command parsing to limit extracted patterns to a maximum of three levels.
- Removed unused security issue detection functions and related tests.
- Improved test coverage for command pattern extraction and validation.
