Function write_opencode_config 

pub fn write_opencode_config(
    compose: &Compose,
    h: AgentHandle<'_>,
    team_mcp_bin: &str,
) -> Result<()>

Write (or clear) the per-agent OpenCode opencode.json. Mirrors write_codex_config: the scoped + full render paths both call it so a mcps: edit flows into the agent at the next render. For non-opencode agents only the managed opencode.json is removed — never the home dir itself, which holds the agent’s session db.
