Submission proposal: Taskade platform entry

Hi maintainers,\n\nI'd like to propose **Taskade** for inclusion if commercial agent platforms are in scope for this list.\n\n- GitHub: https://github.com/taskade/taskade\n- Website: https://taskade.com\n- Description: AI-native workspace platform that combines AI agents, collaborative workspaces, and workflow automation.\n\nSuggested entry:\n\n`- [Taskade](https://github.com/taskade/taskade) - AI-native workspace platform with custom AI agents and automation workflows.`\n\nIf your policy is OSS-only, no worries—just wanted to submit for consideration based on ecosystem relevance.
