- Refactor table display using tablewriter with box-drawing characters and proper Unicode width handling
- Add --as-cron flag to register cron schedules instead of executing immediately
- Implement new 'osmedeus assets' command for asset querying with filtering and statistics
- Enhance workflow parameter display with categorization and per-module summaries
- Improve column width handling and parameter documentation
