Describe your use case

Many enterprise applications and microservices are built using Java. Developers working in Java ecosystems need a native PowerMem SDK to integrate intelligent memory capabilities into their applications without requiring Python runtime or HTTP API wrappers. This would enable:

• Seamless integration with Spring Boot, Jakarta EE, and other Java frameworks
• Type-safe memory operations with Java's strong typing
• Better performance for Java applications (no Python interop overhead)
• Integration with existing Java tooling and build systems (Maven, Gradle)
• Enterprise Java applications requiring memory management for AI features

Describe the solution you'd like

Implement a complete Java SDK for PowerMem that:

1. Core functionality:

   • Memory CRUD operations (add, search, update, delete)
   • User and agent memory management
   • Configuration management (properties files, environment variables)
   • Async operations support (CompletableFuture, reactive streams)

2. SDK structure:

   • Maven and Gradle support
   • Package structure: com.powermem.sdk.*
   • Builder pattern for configuration
   • Exception handling with custom exceptions

3. Features:

   • Full feature parity with Python SDK
   • Support for all memory types (short-term, long-term, private, shared)
   • Multi-agent support
   • User profile management
   • Ebbinghaus forgetting curve integration
   • Hybrid retrieval (vector, full-text, graph)

4. Quality requirements:

   • Comprehensive unit tests (JUnit 5)
   • Integration tests
   • JavaDoc documentation
   • Example projects and tutorials
   • Performance benchmarks

The solution should:

• Follow Java best practices and conventions
• Support Java 11+ (LTS versions)
• Be thread-safe for concurrent operations
• Include proper error handling and logging
• Provide Maven Central distribution
