- Introduced extension methods for recursive serialization and deserialization of nested maps/lists: `toJsonValue()`, `fromJsonValue()`, `toJsonMap()`, `fromJsonMap()`, `toJsonList()`, and `fromJsonList()`. - Updated README.md to include new utilities. - Added tests for JSON value extensions. - Bumped version to 1.4.8.
