fn_task_create gains github_tracking/github_repo params and fn task create gains --github/--no-github/--github-repo flags, resolved through resolveTaskGithubTracking (task > project > global). CLI create now also honors the project/global tracking-enabled default it previously ignored; explicit disables persist enabled:false so later default flips cannot re-enable a task.
