remote actor error: `internal error: dial failure`

[zatevakhin]

issue happens on current main (8eb5486) between two identical instances of qmtcode and identical versions of plugins.

often when prompt is sent it kinda hangs for a while, and then it answers after some time is passed or fails like below.

ACP prompt failed: Error { code: -32603: Internal error, message: "Internal error", data: Some(String("ACP WebSocket session/prompt failed: {\"code\":-32603,\"message\":\"remote actor error: internal error: dial failure\"}")) }

note: more logs should be collected to analyze, current issue created to ensure that's this is an existing problem and not introduced by ongoing refactor.
