Pull Request Overview

This PR implements support for the Arrow C Stream Interface specification, enabling streaming data exchange between different libraries within a single process. The implementation provides both low-level C interface callbacks and a high-level C++ proxy class for managing ArrowArrayStream objects.

Key changes:

• Added arrow_array_stream_proxy class for RAII-based stream management with push/pop operations
• Implemented all mandatory ArrowArrayStream callbacks (get_schema, get_next, get_last_error, release)
• Added check_compatible_schema function to validate schema compatibility when adding arrays to streams
