/**
 * GitHub Copilot CLI client configurator.
 *
 * Copilot is the odd one out: its provider settings are read **only** from the
 * environment. `app.js` resolves `COPILOT_PROVIDER_BASE_URL` (and siblings) via
 * `process.env`, and `~/.copilot/config.json` — which announces itself as
 * "managed automatically" — carries no provider block. There is no file this
 * proxy can write that Copilot will read.
 *
 * So rather than edit a shell profile, which lives outside this proxy's blast
 * radius and runs on every shell the user opens, `apply()` writes a small
 * sourceable script inside the proxy's own directory. The user adds one line to
 * their profile once:
 *
 *   [ -f ~/.neurolink/copilot-env.sh ] && . ~/.neurolink/copilot-env.sh
 *
 * `restore()` deletes the script, so a sourced-but-stale file cannot outlive
 * the proxy — the guard above makes a missing file a no-op.
 *
 * Copilot also honours `OPENAI_API_KEY` + `OPENAI_BASE_URL`, but only when
 * `COPILOT_ENABLE_ALT_PROVIDERS=true` is set; the `COPILOT_PROVIDER_*` path has
 * no such gate, so that is the one used here.
