//! macOS token auto-discovery.
//!
//! README declares macOS/Linux token discovery a non-goal for the MVP. The
//! previous implementation pattern-matched a fixed-length regex against
//! Local Storage files; modern Discord/Chrome encrypt the token via the
//! Keychain on macOS, so the plaintext scan recovers nothing useful and
//! the regex itself missed valid tokens. Until a Keychain-aware port
//! lands, fail clearly and tell the user to use `--token` or
//! `DISCORD_TOKEN`.
