Month 2026-01: Delivered a major modernization of the Mojo type system in modular/modular. Introduced the TrivialRegisterType trait and migrated core type handling away from the older AnyTrivialRegType/__TypeOfAllTypes and the register_passable decorator.

Removed redundant traits, deprecated the decorator, and consolidated type handling into a single cohesive mechanism. The refactor improves type safety, consistency, and future performance potential, while reducing technical debt and paving the way for safer optimizations across CPU/GPU paths.
