/**
 * CwdChanged hook event.
 *
 * Fires when the working directory changes (e.g. via a `cd` command).
 * Observability-only — no decision control. One common use-case is
 * persisting environment variables via `$CLAUDE_ENV_FILE`, which Claude
 * Code also exposes to SessionStart, Setup, and FileChanged hooks. Does
 * not support a matcher.
 * See https://code.claude.com/docs/en/hooks#cwdchanged.
 *
 * @since 0.1.0
