subagent model: opencode-go/glm-5.2 (the cc-ci host is on the Go subscription)

The host's opencode credential is an OpenCode Go subscription key, so ZEN
models (`opencode/…`) fail there with "Insufficient balance". The weekly
run's recipe subagents read this file, so they move to the Go provider.
glm-5.2 rather than deepseek-v4-flash because the latter is China-hosted on
Go and needs a per-workspace opt-in.
