SIENTIAPDE-1646

Enhance orchestration configuration and documentation. Added `RUNTIME` variable to `.env.example`, updated `.gitignore` to exclude `openspec/` and `.cursor/`, and modified `README.md` to clarify queue naming conventions and runtime handling. Refactored activities to use synchronous database and email handling, improving performance and consistency. Updated test cases to reflect these changes and ensure compatibility with new activity definitions.
