/**
 * Agent driver for the Google **Gemini CLI** (`gemini`).
 *
 * Spawns `gemini -p "<prompt>" --output-format stream-json` per turn and maps
 * the stream-json events to the unified {@link AgentEvent} stream. Google /
 * Vertex models only — uses `GEMINI_API_KEY` from `apiKeys.google` /
 * `apiKeys.gemini` / env.
 *
 * @remarks
 * - **Requires Gemini CLI ≥ v0.6.1** — earlier versions reject
 *   `--output-format`. A too-old CLI surfaces as a `process`-category exit error.
 * - **Session resume is not available in headless (`-p`) mode** — the CLI errors
 *   if asked to resume non-interactively, so this driver runs single-turn per
 *   process and logs a warning when a resume id is present.
 * - Exit codes: `42` → input/validation error, `53` → turn-limit (treated as a
 *   completed turn).
