fix(client,nip44): subscription routing and provider-independent NIP-44 (2.0.8) - #538

You have commit messages with errors ⧗ input: fix(ws): explicitly close session on SessionLimitExceededException to restore isOpen()==false reconnect contract Spring's ConcurrentWebSocketSessionDecorator under OverflowStrategy.TERMINATE only sets a private limitExceeded flag and throws SessionLimitExceededException from limitExceeded() — it does NOT close the delegate session. As a result, 2.0.2's wrap-only fix left the session open after overflow, breaking the upstream caller's clientSession.isOpen()==false → reconnect contract that the spec's §6.7d ii originally required. NostrRelayClient.subscribe() and NostrRelayClient.send() now detect a SessionLimitExceededException cause in their respective catch blocks and call clientSession.close(CloseStatus.SESSION_NOT_RELIABLE) explicitly before rewrapping the exception. Non-overflow RuntimeExceptions continue to flow through the existing wrap-as-IOException path unchanged — only overflow terminates the session, matching Spring's OverflowStrategy.TERMINATE semantics that the framework only half-implements. The §6.7d concurrency test now strictly asserts clientSession.isOpen()==false after overflow, restoring the spec's original contract.
