### Purpose Introduce core utility classes for row/array projection, field comparison, partition computation, and internal row helper functions. ### Changes #### `ProjectedRow` - An `InternalRow` implementation that provides a projected (column-selected and reordered) view of an underlying `InternalRow` #### `ProjectedArray` - An `InternalArray` implementation that provides a projected view of an underlying `InternalArray` #### `FieldsComparator` - Compares two `InternalRow` instances field-by-field based on configurable sort fields and ordering - Supports all Paimon data types - Implements Java-compatible floating-point ordering: `-infinity < -0.0 < +0.0 < +infinity < NaN == NaN` #### `BinaryRowPartitionComputer` - Converts between partition string maps and `BinaryRow` representations - Supports all partition column types via `PartitionConverter` #### `InternalRowUtils` - Utility functions for converting between `InternalArray` and `std::vector<std::string>` / `std::vector<std::optional<std::string>>` ### Tests - `BinaryRowPartitionComputerTest` - `FieldsComparatorTest` - `InternalRowUtilsTest` - `ProjectedRowTest` - `ProjectedArrayTest` -- This is an automated message from the Apache Git Service.
