 * settings live in `.gemini/settings.json` within the working directory.
 *
 * A `GEMINI_CONFIG_DIR` env var was requested (google-gemini/gemini-cli#2815)
 * but redirected to XDG spec compliance (#1825), which hasn't shipped as of
 * v0.11.x. Until a flag or env var exists, we use a merge-restore pattern:
 *
 * - **Setup**: read existing `.gemini/settings.json` (if any), save a copy,
 *   merge `mcpServers` into it, write back.
 * - **Teardown** (always, via `finally`): restore the original file, or remove
 *   the file/directory we created.
