Summary
Match dynamic overwrite partitions using their partition transforms.
Why
Partition values stored in data files are post-transform values. Comparing them directly with source columns only works for identity transforms.
What changed
Build predicates over transform(source) for non-identity fields while keeping identity predicates unchanged. Validate each transform against its source field and add bucket and truncate coverage.
The generated expression is intended to be bound by the transform-term predicate support in #1679.
Tests
go test ./table/internal -run TestBuildPartitionMatchPredicate -count=1
