`open_client_proxy()` broadcast its one-slot linked channel to an
always-running status relay and an idle method receiver. Status
traffic advanced only the relay, so the first lazy contract lookup
for an uncached order raised `Lagged` before receiving its
response.
Give `relay_client_proxy_messages()` sole receive ownership. Route
tagged responses from concurrent caller tasks into their per-`mid`
slots while each proxy context retains its own channel and relay.
Deats,
- log stale responses with their original method name;
- warn when unresolved-request metadata exceeds its bounded limit;
- drop late responses after caller cancellation;
- preserve the reconnect design note and message-case rationale;
- accept clean channel EOF during proxy teardown;
- cover idle status, concurrency, cancellation and EOF paths.
