/**
 * Gemini CLI client configurator.
 *
 * Gemini CLI was reachable through the proxy long before this file existed —
 * `GOOGLE_GEMINI_BASE_URL` pointed at the proxy's `/v1beta` door works — but
 * nothing wrote it, so every user had to know that and export it by hand. The
 * proxy already serves the door (`geminiProxyRoutes`, `POST
 * /v1beta/models/{model}:generateContent`); this only closes the onboarding
 * gap.
 *
 * **Why a file and not an env script.** Copilot is configured through
 * `~/.neurolink/copilot-env.sh`, which the user must source from their shell
 * profile. On the machine this was developed against, nothing sourced it: the
 * writer reported success, `applyAllClients` counted it applied, and Copilot
 * had never once used the proxy. A file the CLI reads on its own has no such
 * silent-failure mode. Gemini CLI loads `~/.gemini/.env` (its own error text
 * says "set it in your environment or ~/.gemini/.env"), so that is what this
 * writes.
 *
 * The snapshot lives in `~/.neurolink/`, following `codex.ts`, never inside
 * the file being managed — see `openCode.ts` for what that cost.
