Update .gitignore to include log files and database journal files. Modify go.mod to update dependencies for go-sqlite3 and cloud.google.com/go/compute/metadata. Enhance Makefile to include logging options for manager and runner commands. Introduce new job token handling in auth package and implement database migration scripts. Refactor manager and runner components to improve job processing and metadata extraction. Add support for video preview in frontend components and enhance WebSocket management for channel subscriptions.
