The per-connection / per-session ConnectionState this request is bound to.
A transport that scopes state per peer returns the state it
resolved for THIS request: the SessionManager-owned state looked up by
Mcp-Session-Id (stateful HTTP), or a fresh per-request state built from the
request's effective version + _meta (stateless HTTP). Returns null when
the context carries no such state, in which case the server core falls back
to its single bound activeConnection (stdio / bare-handle).
