/**
 * Canonical WrongStack messages/tools → OpenAI **Responses** API wire shapes.
 *
 * Used by the `openai-codex` family (ChatGPT backend). The Responses API takes
 * a flat `input` array of typed items rather than chat/completions `messages`:
 *   - user text/image     → { role:'user', content:[{type:'input_text'|'input_image', ...}] }
 *   - assistant prose      → { type:'message', role:'assistant', content:[{type:'output_text', ...}] }
 *   - assistant tool call   → { type:'function_call', call_id, name, arguments }
 *   - tool result           → { type:'function_call_output', call_id, output }
 *
 * `thinking` blocks are intentionally dropped from the input: replaying them
 * would require the opaque `reasoning.encrypted_content` blob (which we don't
 * persist), and omitting them — plus omitting function-call item ids — sidesteps
 * the Responses reasoning/tool-call pairing validation entirely.
