Enhancements: • Annotate overriding methods and dunder implementations with @OverRide throughout core, CLI, logging, hub, and plugin services. • Tighten type hints for several methods, including exit codes and CLI entrypoints, to better align with their actual behavior. Build: • Configure type-checking rules to treat missing override decorators as errors in the ty configuration. meltano/meltano
