Module abi 

Stable C ABI contract between Daft and extension cdylibs.

This module defines the repr(C) types that Daft and extension shared libraries use to communicate. It has zero Daft internal dependencies and zero Arrow implementation dependencies (unless a feature flag is enabled).

Naming follows Postgres conventions:

• “module” = the shared library at the ABI boundary
• “extension” = the higher-level Python package wrapping a module
