opencode‑cli v1.18.13 freezes after selecting LLM‑runtime inside VS‑Code when CC‑Switch runs for Claude‑Code

Description

Windows environment. When I enable the routing service of CC‑Switch to run Claude‑Code inside VS‑Code, all integrated VS‑Code terminal child‑processes inherit CC‑Switch’s MCP named‑pipe handle.
After I launch opencode‑cli 1.18.13 in the VS‑Code terminal, it hangs right after the prompt "llm runtime selected opencode". No outgoing HTTP request gets sent to the LLM server.
The freeze will not occur when I start opencode‑cli from a standalone native CMD window outside VS‑Code.
I have disabled opencode traffic interception inside CC‑Switch, yet the persistent MCP named‑pipe still triggers the hang‑up during opencode‑cli’s local MCP‑service discovery stage.
