调研方向
Start by tracing how the server stream handler represents the protocol's UNCAUGHT_ERROR and how errors thrown outside the main handler currently behave. Define the ctx.uncaught entry point so a callback or background task can end the request with the same semantics as throwing inside the handler, then verify streaming requests receive the expected internal error.

描述
UNCAUGHT_ERROR is built into the protocol, it means the server encountered an internal error in processing the request.
We've noticed that people use this correctly when using unary rpcs but not all the time in streaming rpcs. The reason being is that if you're outside the main handler function (i.e. in a callback or background task), you have no way of triggering an internal error, throwing will not be caught by the handler.
This leads people to define error types that are basically unhandlable by the client and are effectively custom internal errors. This leads to bad error hygiene on the client side.
We should have a way to basically end the request with an uncaught, something like ctx.uncaught(new Error("something went wrong")), which would end the request following similar semantics as throwing within the handler.
