Crate zagens_runtime_adapters 

Runtime adapters — MCP, session persist, snapshots (D16 E1-a, D17 frozen).

Extracted from zagens-cli as part of the D16 sidecar crate split. Further migration of engine, tools, and route handlers is deferred by design (D17 Architecture Freeze) — those remain internal co-located units in zagens-cli, not candidates for crate extraction. This crate is the stable boundary for MCP connectors, persistence adapters, scratchpad gates, snapshots, and network policy.
