Create OsSecureStore: A cross-platform secure credential storage library

This commit introduces OsSecureStore, a Java library that provides secure storage
for sensitive data like tokens, passwords, and credentials using platform-native
security features:

Key components:
- Core API with OsSecureStore static methods for basic secure storage
- SecureDataManager for organized credential management
- Platform abstraction layer for cross-platform support
- Native Windows DPAPI integration via JNI
- Automatic application name detection
- Secure data persistence in OS-appropriate locations

Technical details:
- Platform-specific implementations through PlatformSecureStorage interface
- Windows implementation using Data Protection API (DPAPI)
- JNI bridge between Java and native Windows security features
- Base64 encoding for encrypted data storage
- Auto-extraction of native libraries
- Prefix-based namespace isolation for stored credentials

Future extensibility:
- Architecture designed for macOS and Linux implementations
- Clean interfaces for adding new platform support

Testing:
- Comprehensive WindowsSecureStorageTest implementation for all features
- Edge case testing for storage reliability

The library is designed to be a comprehensive solution for securely storing
sensitive application data while leveraging OS-level security capabilities.
