* Fix all remaining Jackson deprecation warnings

- Replace deprecated ParserMinimalBase constructor with StreamReadConstraints
- Add non-deprecated location methods (currentTokenLocation, currentLocation)
- Update GeneratorBase constructor to use 4-parameter form with IOContext and JsonWriteContext
- Add new createKeySerializer method signature for Jackson 2.18
- Keep deprecated methods for backward compatibility

All tests pass and Jackson deprecation warnings are eliminated.
