/**
 * Spinner - a minimal terminal progress animation (the "turning thing").
 *
 * On an interactive terminal (TTY) it renders an animated spinner that updates
 * in place. On a non-TTY stream (pipe, file, CI logs) it degrades gracefully:
 * the animation is skipped and only the final status line is emitted, so piped
 * output stays clean.
