- Introduced benchmark tests for JSON and binary marshaling/unmarshaling, canonical encoding, and ID generation to assess performance.
- Implemented optimizations to reduce memory allocations and CPU processing time across various encoding methods.
- Enhanced `Marshal`, `ToCanonical`, and `MarshalBinary` methods with pre-allocation strategies to minimize reallocations.
- Added handling for nil tags to avoid unnecessary allocations during binary encoding.
- Documented performance improvements in the new PERFORMANCE_REPORT.md file, highlighting significant reductions in execution time and memory usage.
