Refactor skill handling and improve runtime trace capabilities

- Removed the selectSkill method from prepareService and adjusted related logic in the Run method of Service.
- Updated tool catalog to parse agent allowed tool codes directly.
- Simplified Request and RunInput structures by removing unnecessary fields.
- Enhanced the RuntimeTraceCollector to manage skill activation and visibility.
- Introduced a new databaseSkillBackend to manage skill definitions and their metadata.
