0.0.9

Summary

Added comprehensive MessagePack timestamp extension type (-1) support and significantly expanded test coverage for the zig-msgpack library.

Key Features

🕐 Timestamp Extension Support

• Support for all three MessagePack timestamp formats per specification:
  • 32-bit timestamp: Seconds-only for 32-bit unsigned integers
  • 64-bit timestamp: Nanosecond precision with 34-bit second range
  • 96-bit timestamp: Full range with signed 64-bit seconds + 32-bit nanoseconds
• Automatic optimal format selection based on value ranges
• Seamless integration with existing serialization/deserialization logic

🧪 Comprehensive Testing Enhancement

• Boundary testing for all MessagePack formats (array32, map32, str16/32, bin16/32, ext8/16/32)
• Edge case coverage (NaN/infinity floats, int64/uint64 boundaries, error conditions)
• Format marker verification and Unicode string support
• Memory management validation and timestamp-specific tests

📚 Documentation Improvements

• Updated README.md with timestamp usage examples and API documentation
• Added Chinese translation (README_CN.md)
• Enhanced usage examples and error handling documentation

Technical Implementation

• Strict adherence to MessagePack timestamp specification (extension type ID -1)
• Nanosecond precision validation (0-999,999,999)
• Full Unix timestamp range support including pre-1970 negative values
• Maintains backward compatibility

Breaking Changes

None. Fully backward-compatible additive functionality.

Performance Impact

Minimal. Negligible timestamp support overhead with optimal storage efficiency through automatic format selection.
