/**
 * Agent Auth Detector Service Interface
 *
 * Output port for detecting whether the user is authenticated with a given
 * AI coding agent (Claude Code, Cursor, Gemini CLI, Copilot CLI, etc.).
 *
 * Implementations are platform-specific: they may inspect environment
 * variables, credentials files, the macOS Keychain, or call agent-specific
 * `auth status` subcommands. Keeping this behind an output port keeps the
 * application layer free of node:fs / child_process / keychain imports and
 * lets tests substitute a fake.
