* Enhance null-safety annotations across modules and refactor for improved consistency: - Added `null!` annotations to enforce non-nullability expectations. - Updated workflows, tests, and runtime services to handle default null values reliably. - Removed obsolete and unused APIs, simplifying interfaces and improving maintainability. - Refactored methods and properties for clarity, thread-safety, and consistency. - Adjusted test configurations for code coverage tracking and integration improvements. * Refactor activity iteration in container serialization tests to simplify type casting.
