Goal

Add MCP interoperability without leaking wire-version behavior into rlm_agent or rlm_graph.

Scope

define canonical internal MCP request/result/error/tool/resource/prompt terms;
implement transport abstraction for stdio and Streamable HTTP where applicable;
implement MCP 2025-11-25 lifecycle: initialize, capability/version negotiation, notifications/initialized, and session handling;
support MCP-Protocol-Version and MCP-Session-Id semantics;
normalize tool/resource/prompt discovery and invocation into canonical terms;
recover cleanly from invalidated legacy sessions;
expose selected version/transport in traces.

Acceptance criteria

prolog-rlm client interoperates with a 2025-11-25-only server fixture;
prolog-rlm server accepts a 2025-11-25-only client fixture;
session invalidation triggers a bounded re-initialize/retry path;
version-specific code remains inside the 2025 adapter;
agent/graph modules only see canonical MCP terms.
