Summary

Summary by CodeRabbit

• Refactor
  • Reorganized the internal implementation of Parquet hybrid scanning into a dedicated area. The public interface and scanning behavior remain unchanged, so existing workflows for reading Parquet data continue to work as before. No changes to hybrid scan inputs or data flow are included.

Hybrid-scan implementation files move into a dedicated source directory and internal namespace. The public experimental namespace remains unchanged. Constructor inputs and forwarding behavior remain unchanged.

Changes: Hybrid-scan relocation

Layer / File(s)	Summary
Update hybrid-scan declarations cpp/include/cudf/io/experimental/hybrid_scan*.hpp, cpp/src/io/parquet/hybrid_scan/*_helpers.hpp, cpp/src/io/parquet/hybrid_scan/hybrid_scan_impl.hpp, cpp/src/io/parquet/hybrid_scan/page_index_filter_utils.hpp	Implementation pointers, forward declarations, and helper declarations now use cudf::io::parquet::hybrid_scan::detail.
Relocate implementation and build entries cpp/CMakeLists.txt, cpp/src/io/parquet/experimental/hybrid_scan*.cpp, cpp/src/io/parquet/hybrid_scan/*	Implementation definitions and constructor references use the new detail namespace. The CMake source list uses the hybrid-scan directory for the relocated sources.

Full details: Title check

Explanation

The title names the main change: moving Parquet hybrid scan internals out of the experimental namespace. The raw summary and the description confirm the move from src/io/parquet/experimental to src/io/parquet/hybrid_scan and the new cudf::io::parquet::hybrid_scan::detail namespace. The title is specific and matches the changeset.

Full details: Description check

Explanation

The description states that the PR moves Parquet hybrid scan internals from src/io/parquet/experimental to src/io/parquet/hybrid_scan and names the new namespace cudf::io::parquet::hybrid_scan::detail. This directly describes the changeset, so the check passes.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2.
