Approved design for restructuring go-mlx:
- Root package becomes clean interface (TextModel, LoadModel, Token)
- All CGO code moves to internal/metal/
- Deterministic memory management (Close + per-step cleanup)
- Error propagation instead of silent logging
- mlxlm/ backend placeholder for Python subprocess support
Includes API breaking change communication in FINDINGS.md and
memory management research tasks in cpp/TODO.md.
