/**
 * Human-friendly relative-time formatter ("3d ago", "just now").
 * Used in feed + feedback output where exact timestamps are noise.
 *
 * Past-only by design — every caller is reading historical events
 * (when a comment was posted, when a skill was last edited). Future
 * dates fall through to the "just now" branch rather than printing
 * gibberish; surfaces a clock-skew bug as the most-recent timestamp.
