Remove most uses of @MaxMindDbConstructor
With maxmind-db 4.0.0, records automatically use their canonical constructor for deserialization when no constructor is explicitly annotated with @MaxMindDbConstructor. This change removes the annotation from most records in the codebase. Changes: - Removed empty canonical constructors from records with no logic - Removed @MaxMindDbConstructor from canonical constructors with immutability/validation logic, relying on automatic detection - Added useDefault=true to boolean parameters to leverage automatic null-to-false conversion instead of manual Boolean→boolean handling - Kept @MaxMindDbConstructor only for records requiring custom type conversions (String→LocalDate in AnonymousPlusResponse, String→enum in ConnectionTypeResponse and Traits) - Removed unused MaxMindDbConstructor imports All tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
