stream rpc能否搭配dynamic partition channel使用

**Describe the bug (描述bug)**

请教一下，下游n个server一致性哈希。上游能否使用stream rpc连接dynamic pattition channel，并且在切换连接是stream rpc应用层能感知到，并且能够重新发起握手RPC？

**Additional context/screenshots (更多上下文/截图)**

No source files, tests, versions, or reproducible steps are provided. Start by locating the stream RPC and dynamic partition channel entry points, then determine whether connection changes reach the application and whether a handshake can be retried. Done would require a documented, reproducible answer or a clearly scoped implementation plan.
