a7e9f8843b experiment(re): expose native CFG and value identities for composition
[AUTOMATED] Preserve the opt-in pinned Kuna exporter as a reproducible source patch. Share typed graph/value reads and derived control dependence through the SDK, CLI and MCP adapters, retaining unknown runtime and memory semantics.

Validated 29 focused tests, lint, actual diagnostic/native MCP workflows and a real zlib CLI composition. C and line mappings match the prior stock capture. Full upstream corpus/workspace gates and revised real-model costs remain unverified.
