fix(coderd/x/chatd): avoid closing poller hint channels (#28746) - #28976
Merged
Conversation
Closes SEC-515 Prevent a `send on closed channel` panic when a chat stream unregisters during polling. The poller no longer owns or closes subscriber channels. This is safe because delivery is guarded by the stream context, and unregister removes the subscriber from future polls. (cherry picked from commit ced03dc)
