/**
 * Credential feed for the live multi-account CI lane (#9960).
 *
 * Reads the machine's connected coding-agent credentials — the Codex
 * `~/.codex/auth.json` (refreshed via the same refresh logic the runtime uses)
 * and the Claude Code OAuth token — and emits the minimal blobs that
 * `live-multi-account-e2e.ts` seeds the pool from, so a scheduled lane can run
 * real-account rotation. Pair this with a scheduled refresh (the Codex token is
 * short-lived) to keep the CI secrets live.
 *
 * Usage:
 *   bun scripts/export-ci-account-secrets.ts [--index N] [--out FILE] [--gh]
 *
 *   --index N   suffix for the emitted var names (default 1) — run once per
 *               connected account, bumping N, to seed 2× each for rotation.
 *   --out FILE  append `NAME=value` lines to FILE (a dotenv for the runner).
 *   --gh        print `gh secret set` commands (review before running).
 *
 * Env overrides:
 *   CODEX_AUTH_PATH               path to auth.json (default ~/.codex/auth.json)
 *   CLAUDE_CODE_OAUTH_TOKEN       the Claude token to export (else skipped)
 *
 * Secrets are printed to stdout — run in a trusted shell, never in CI logs.
