Diagnostics with the code that caused them
strider check folds formatting drift, style policy, and package-aware correctness analysis into a single diagnostic pass. It is read-only by default, with explicit safe and unsafe fix modes when source should be updated. No plugin zoo, no tool matrix — files are parsed once and shared across every selected check.
