/**
 * Claude Code config helpers for logins Crewly performs.
 *
 * Claude Code shows two interactive screens that an agent PTY cannot get
 * past, and a login done through Crewly (token or API key in the env) does
 * not dismiss either of them:
 * - the first-run theme picker ("Choose the text style"), shown until
 *   `hasCompletedOnboarding` is true in `~/.claude.json` — Crewly already
 *   refuses to start agents while it is up (CLAUDE_STARTUP_BLOCKERS);
 * - "Detected a custom API key … use it?", shown for an `ANTHROPIC_API_KEY`
 *   whose last 20 characters are not in `customApiKeyResponses.approved`.
 *
 * After a successful Crewly login these helpers record both answers, the way
 * Claude Code itself does when a person answers them. Other keys in the file
 * are preserved; an unreadable file is left untouched.
 *
