MCP components now resolve through shared `resolve_*` helpers that make `create_fresh` deep copies instead of sharing singleton state, and a fresh session is minted per call whenever `session_id` is omitted. One request can no longer pick up another's history or state, so concurrent MCP traffic stays cleanly isolated.
