feat: Add log category filtering for enhanced logging control

- Introduced a new command-line flag for specifying log categories, allowing users to filter logs based on selected categories.
- Implemented parsing of the comma-separated log categories string in the main application.
- Enhanced the LogManager to support category-specific logging and added console output to indicate which categories are enabled for debugging.
