Caution Review failedThe pull request is closed. WalkthroughThe codebase was refactored to introduce a dual-arena memory management model for the CSV reader, separating persistent and temporary allocations. Initialization and configuration functions were updated to accept two arenas. A new standalone initialization function was added, and all memory allocations in parsing and reading logic were updated accordingly. Tests were modified to use the new standalone initialization.
