Summary
Root cause
The observed codex_apps failures can happen before normal tool execution: RMCP startup fails while sending initialize, or the first read-only tools/list fails after startup. Retrying hosted_apps_bridge tools/call would not cover initialize and would risk replaying side-effecting tool calls. This change retries the streamable HTTP handshake itself, recreates the transport between initialize attempts, and retries only tools/list among post-initialize service operations.
