- Removed V1-specific code paths in favor of V2 with toV1() conversion
- Simplified pointer handling to use a single internal representation
- Made entityLabel configurable in setProperty()
- Updated tests to use buildV1() and buildV2() explicitly
- Removed unused time utility module
- Added more comprehensive test coverage for entity properties
This change makes the DeltaBuilder more maintainable by reducing code duplication and following the pattern of building V2 deltas first, then converting to V1 when needed.
- Implemented DeltaBuilder class with support for both V1 and V2 delta formats
- Added comprehensive test coverage for all builder functionality
- Included utility function for microsecond-precision timestamps
- Added support for transactions and negation via special pointer contexts
- Provides type-safe API for creating deltas with proper validation
