Tracks progress through the swamp Genesis quest campaign. Parses `swamp quest --json`, persists each progress snapshot as swamp data, and guards against XP regression — since the anti-abuse penalty zeroes a score, a backward slide in passXp, tier, or challenge progress is the tell-tale signal and is surfaced as `regressed`. `check` records a snapshot and diffs it against the previous one; `advise` ranks the closest incomplete challenges toward a target tier so an operator (or workflow) knows the cheapest next move.
