Module abi 

C ABI compatibility layer (§4, §14).

This module implements the external C-compatible world:

• Types, structs, constants matching upstream layout
• C ABI exports (libxml2.so.2, libxslt.so.1)
• Callbacks, allocator hooks, ownership membrane
• Versioning macros and runtime reporting

Phase 0 status

This module is scaffolded. The ABI membrane will be constructed in Phase 1 (Compatibility Skeleton, §85 Phase 1) after the archaeological atlas is complete. See atlas/PARITY_MATRIX.md for current API completeness metrics.
